Question

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 month Molly purchased 4 movie tickets and earned $17. Solve this equation justifying each step with an algebraic property of equality.

Answer 1

she purchased

8 books last month.

Explanation:

Answer 2

the algebraic expression is 4(0.25)+2x=17

STEP 1: Simplify both sides of the equation

1+2x=17 or 2x+1=17

STEP 2: Subtract 1 from both sides

2x=16

STEP 3: Divide both sides by 2

2x/2 = 16/2

x=8
