angle works at AutoZone and makes $72 dollars a day and extra $8 for each platinum membership card he sells. angles goal is to make $200 today. how many memberships cards must he sell?
First, I subtracted 72 from 200 and that gave me 128. Then, I divided 128 by 8 and got 16. To check my work I multiplied 16 by 8 and got 128. Then I added 72 to 128 and got 200.
