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

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
