If there was a cash voucher of $50 given when the total amount of the items bought is over $500, and the voucher could be used at once. (a) Round down the prices of each item to the nearest ten, calculate the total selling price. (b) Could Cecila used the cash voucher? If so, how much should she pay for?
最佳解答:
selling price: 173+89.6+229.4+39.9=531.9 round off to nearest ten is $530 Cecila could use the cash voucher and she has to pay 531.9-50=$481.9 round off to nearest ten is $480.
