A.
$220
B.
$250
C.
$255
D.
$270

Answer 1

D. $270

Explanation:

$55 per hour for 4 hours = $55 * 4 = $220

$50 service fee

total = hourly amount + service fee

total = $220 + $50

total = $270

Answer 2

The correct answer is D.

$55 per hour x 4 hours = $220

$220 + $50 service charge = $270 total

Hope this help.
