NEED HELP FOR THIS QUESTION I want to buy some Botswana pulas and the exchange rate is 8.25 BWP = £1 if I buy them abroad using a credit card or 8.5 BWP = £1 for a cash transaction at a Bureau de Change. The credit card company will charge me 2.3% commission on a credit card transaction whereas a Bureau de Change charges 2% commission plus a fee of £3.

Write down an expression for the cost (including commission) of buying a particular number of Botswana pulas

(a) by credit card and

(b) from a Bureau de Change.

c. Evaluate each of these expressions for 700 BWP, 800 BWP, and 1000 BWP respectively.

d. Hazard a guess as to the number of pulas you would have to buy for the cost to be the same whether you use a credit card or cash.
