erica earns a rebate each month on her meals and movie tickets. she earns $3 for each movie ticket and $0.80 for each meal. last month erica purchased 15 meals and earned $18.

part a: create an equation that will determine the number of movie tickets she purchased.

part b: solve this equation justifying each step with an algebraic property of equality.

part c: how many movie tickets did erica purchase last month?

part A-

3t + .80m = 18 (t - tickets) (m - meals)

we already know m = 15 so our equation would turn into

3t + .80(15) = 18

3t + 12 = 18

part B-

3t + 12 = 18

subtract 12 from both sides

3t + 12 = 18

-12 -12

then, 3t= 6

and, we know 3 goes into 6 two times meaning t=2

part C- Erica purchased 2 movie tickets last month
