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. part a: create an equation that will determine the number of books she purchased. (3 points) part b: solve this equation justifying each step with an algebraic property of equality. (6 points) part c: how many books did molly purchase last month? (1 point)

The algebraic equation is 4(0.25)+2x=17

STEP 1: Simplify both sides of the equation

1+2x=17  or  2x+1

STEP 2: Subtract both sides

2x = 16

STEP 3: Divide both sides by 2

2x/2 = 16/2

x = 8

Molly purchased 8 books last month

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
