Answer:
3.4 Hours
Step-by-step explanation:
25 x $7.75 = $193.75
$250 - $193.75 = $21.25
$21.25/$6.25 = 3.4 hours
You must work 3.4 hours at the second job.
Subtract 13.09 from 21.59 giving you 8.5. Since the amount of space on both the left and right margin have to be equal you would divide by 2 to get 4.25 on the left margin as well as the right.
