Answer :
a) To calculate the cost of a 330ml tin of Coca Cola in June 2017 when the average price was R7.75 and there was a 7% increase from 2017 to 2018, we need to first calculate the original price in 2017.
Let x be the cost in June 2017:
x + 7% of x = R7.75
x + 0.07x = R7.75
1.07x = R7.75
x = R7.75 / 1.07
x ≈ R7.24
Therefore, the cost of a tin of Coca Cola in June 2017 was approximately R7.24.
b) To calculate the cost of a 330ml tin of Coca Cola in June 2018 in Botswana if the exchange rate was 1 Rand = 0.77 Botswana Pula:
Cost in Rands = R7.75
Cost in Botswana Pula = R7.75 / 0.77
Cost in Botswana Pula ≈ 10 Botswana Pula
a) If James received R11,400 as pocket money for his trip to Britain and the exchange rate was £1 = R20.80, we can calculate the amount in pounds he will get:
£1 = R20.80
Therefore, £11,400 / 20.80 = £547.12
James will get approximately £547.12.
b) Comparing the exchange rates of £1 = R20.80 and £1 = R17.268, we can see that the pound is considered stronger than the Rand.
c) If Faith bought a handbag for her mom costing €125 and claimed that it cost her less than R2,000, we can calculate the maximum amount in Rands based on the exchange rate:
€1 = R17.84
Therefore, €125 = 125 * 17.84 ≈ R2,230
This verifies her claim because the amount she paid (R2,230) is indeed less than R2,000.
a) The exchange rate the bank will use to exchange the club's £500 will be the SELL rate which is R18.087.
b) Calculating the Rand amount the club will receive from £500:
Amount in Rand = £500 * R18.087 ≈ R9,043.5
Therefore, the club will receive approximately R9,043.5 from £500 GBP after the bank charges are deducted.
Let x be the cost in June 2017:
x + 7% of x = R7.75
x + 0.07x = R7.75
1.07x = R7.75
x = R7.75 / 1.07
x ≈ R7.24
Therefore, the cost of a tin of Coca Cola in June 2017 was approximately R7.24.
b) To calculate the cost of a 330ml tin of Coca Cola in June 2018 in Botswana if the exchange rate was 1 Rand = 0.77 Botswana Pula:
Cost in Rands = R7.75
Cost in Botswana Pula = R7.75 / 0.77
Cost in Botswana Pula ≈ 10 Botswana Pula
