Nathan earned $63 for working 7 1/2 hours.. How much does Nathan earn per hour? 0 $8.40
O $7.20
$8.90
O $9.50

$8.40

Step-by-step explanation:

We have to find the unit rate, so our equation is:

63 ÷ 7 1/2 = 8 2/5 or 8.4

So Nathan earns $8.40 per hour

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
