Answer:
$65.34/day
Explanation:
1. We first need to find out how much money was spent in total and to do this we subtract the total amount from the leftover amount:
$1,000 - $542.62 = $457.38
2. To find out the daily cost we simply divide it by the number of days which is 7 in this case, because 1 week = 7 days.
$457.38 ÷ 7 = $65.34
