Ryan works at at the donut shop where he makes $10.25 per hour . He also works part time at the school bookstore where he makes
$8.75 per hour . If he worked 20 total hours last week and made $196 , how many hours did he work at the bookstore
1 answer:
Answer:
6 hours
Step-by-step explanation:
Let
x----> the number of hours worked at the donut shop
y----> the number of hours worked at the school bookstore
we know that
x+y=20
x=20-y -----> equation A
10.25x+8.75y=196 -----> equation B
Substitute equation A in equation B and solve for y
10.25(20-y)+8.75y=196
205-10.25y+8.75y=196
10.25y-8.75y=205-196
1.5y=9
y=6 hours at the school bookstore
