 Mr du Plessis gets the account for his electricity consumption over 2 months (see above bill). He has three electricity meters on his property for two small houses and a flat on the premises and they are billed together.

1.                    
   1. What is the total amount due? (1)
   2. What does “billing period” mean and how long is it in this case? (4)
   3. When did Mr du Plessis last pay his electricity account and how much did he pay? (2)

   3. Can you see a pattern between the high points (spikes) on the graph and the number of months that has passed? What does this pattern suggest about how often Mr du Plessis’ metre is read? (3) [25]

Solutions

1.                                
   1. R4 963,42 ✓
   2. The billing period is a specific number of days ✓ covered by the invoice. The standard billing period is one month. ✓ In this case it is 61 days ✓, so this invoice includes electricity consumption for the 61 days before the billing date. ✓   (4)
   3. His last payment was on 2012-06-27, for R2 520,25. ✓✓   (2)
   4. The amount is negative to indicate that R2 520,25 ✓ was subtracted from what Mr du Plessis owed. (This payment is called a credit ✓ – it is money being paid into the account). ✓   (3)

   5. “Balance brought forward” is the amount of money from the previous ✓ invoice that must be paid, or is still outstanding. In this invoice, the amount still outstanding was due to be paid by 2012-07-14 ✓, and Mr du Plessis paid it in full on 2012-06-27. ✓    (3)

2.                                                         
3. 1. If the third meter is for the small flat on the property, for example, then the consumption will be lower ✓ because there will be fewer ✓ lights and plugs.(2)
   2. One major factor that affects how much electricity people use is the weather. In winter, ✓ for example, people use more ✓ lighting (because it gets dark ✓ earlier), heaters, electrical blankets, and appliances like tumble driers. (any 2)   (2)
4.                                    
   1. The letters under the graph stand for the months of the year. They are not in the usual order (J (January), F (February), M, A, etc.) ✓ but are arranged in the order of the last months starting 12 months ago and ending with the most recent month (J (July), A (August) ✓, S (September) to J (June)).
   2. The large spikes indicate when the meter reading for consumption was high ✓, and the flat segments of the graph indicate that it was at 0kWh ✓. It is unlikely that Mr du Plessis used no electricity in the months when the meter reading was zero – it is more likely that the meter was not read at
      all (for example, if no one was home when the meter reader arrived) in those ✓ months, and so consumption was entered into the system as being 0kWh. (3)
   3. Initially, the peaks in the graph occur once every three months ✓ (July, October, January, April). Then the graph changes and there are non-zero readings for April and May ✓, no reading for June and again a reading for July ✓. So, from July 2011 to April 2012, the meter was read once every 3 months. Then it was read for 2 consecutive months (April and May), and then again two months later. (3) [25]

Activity 5

Consider the previous activity, where Douglas planned to travel to Durban. He eventually decided to travel to Durban using bus Option 1. He kept all the receipts and till slips so that he could write a statement to see how much money he actually spent. Read the summary below of Douglas’s bus trip.
When Douglas arrives at the bus station to buy the ticket, he finds that the advertised price does not include VAT, and he needs to add 14% to the cost. To add to his problems, the bus breaks down and Douglas needs to find a place to stay the night in Knysna. He finds a backpackers’ lodge that costs R200 a night for a shared room. He also needs to rent a locker for R20 to keep his luggage safe. Apart from three meals on the bus, he needs to buy an extra supper and breakfast, which cost him R30 each.

1. Fill in a table like the one used for his budget, to show his actual expenses and the running total of expenses.
   

   Expense description	Amount	Running total of expenses

2. What is the amount of money he ends up with as spending money in Durban?
   Remember: he had R2 500 to begin with.

Solutions

1.                  
   

   Expense description	Amount	Running total of expenses
   Bus Fare	R1 200 + R168 VAT	R1 368
   Meals on Bus	R90	R1 458
   Backpacker’s accommodation	R200	R1 658
   Locker	R20	R1 678
   Meals	R30 × 2 = R60	R1 738

2. He has saved R2 000 and received R500 from his parents.
   R2 500 - R1 738 = R762 to spend in Durban

Solutions

1. 20 ´ R500 = R10 000 ✓
2. R2 500 ✓
3. R5 500 ✓
4. R2 500 + R250 = R2 750 ✓
5. R800 + R96 = R896 ✓
6. R1 200 ´ 2 = R2 400 ✓
7. Taxi fare: R10 per day ´ 2 children ´ 20 days ✓ =R400. ✓
   Petrol: (20 × 4 litres ×R10,50) ✓ + (10 × 3 litres × R10,50) ✓ = R1 555 ✓
8. Total salaries = R19 ✓ 5% of this is R975. ✓
9. 5% of R9 500 ✓ = R475. ✓
10. Total income = salaries ✓ + additional income ✓ = R19 500 + R2 500 ✓
    = R22 000. ✓ 5% of this is R1 100. ✓
11. 550 × R 0,50 ✓ = R275; ✓ monthly is R275 ✓ + R200 = R475. ✓
12. The total for fixed expenses is R12 621 ✓. The total for variable expenses is R5 755 ✓. So, the total for all expenses is R18 376. The total income for the household is R22 000, so yes – they are within budget ✓, because their income is greater than their total ✓ expenditure and they have a surplus of money. ✓

   0 – 160 000		18% of each R1
   160 001 – 250 000		28 800 + 25% of taxable income above R160 000
   250 001 – 364 000		51 300 + 30% of taxable income above R250 000
   364 001 – 484 000		81 100 + 35% of taxable income above R346 000
   484 001 – 617 000		128 400 + 38% of taxable income above R484 000
   617 001 and above		178 940 + 40% of taxable income above R617 000
   TAX REBATES:	Primary rebates – R11 440 Secondary Rebates (persons 65–75 years) – R6 390 Tertiary Rebates (persons 75 years and older) – R2 130
   TAX THRESHOLD:	Below age 65 years – R63 550 Age above 65 years to below 75 – R99 056 Age above 75 years and older – R110 889
   EXAMPLE	R556 444 (yearly salary) R128 400 + 38% of amount above R484 000 (R556 444 – R484 000) = R128 400 + 38% × R72 444 = R155 928,72 – R11 440 = R144 488,72 (yearly tax) ∴R12 040,73 (monthly tax)
