Answer:
$1.89
Step-by-step explanation:
Let's add all the prices and the sales tax:
$2.15 + $0.98 + $1.54 + $3.05 + $0.39 = $8.11
Two five-dollar bills equals $10.00, so we will subtract the total from this.
$10.00 - $8.11 = $1.89
This means Muriel will receive $1.89 in change when using two five-dollar bills.
