The answer would be B. $2.25.
We already know the cost of the dehumidifier, which is $162.75. Now we need to find out how much Paul gave the sales clerk in cash.
1 fifty dollar bill= $50
4 twenty dollar bills= $80
7 five dollar bills=$35
Altogether this equals $165. So in order to find out how much change Paul should get, subtract the cost of the humidifier from the amount Paul paid.
$165-$162.75=$2.25
Paul should receive $2.25 in change.
