Molly earns a rebate each month on her movie tickets and books. She earns $0.25 for each movie ticket and $2 for each book. Last

stiv31 [10]

Answer:

8 books

Step-by-step explanation:

Earning for each ticket is $0.25 and for each book is $2

If total earning for 4 tickets and x books is $17, then the equation is:

0.25*4 + 2x = 17
1 + 2x = 17
2x = 16
x = 16/2
x = 8

So Molly purchased 8 books
