Answer:
37
Step-by-step explanation:
Emily = x
Samantha = x + 2
Lauren = x + 4
x + (x + 2) + (x + 4) = 42
x = 12
Thus:
Emily = 12
Samantha = 14
Lauren = 16
The answer is 270 found out by google calculator.
$7.95 x h = $236.50
$7.95 x 18 = $143.10
$236.50 - $143.10 = $93.4
7.95 x h = $93.4
$93.4 / $7.95 = 11.7 hours
h = 12 hours
