Answer 6

they give you revenue, so you can plug in 67.50 for y and solve for x

67.50 = 2.50x + 20 ?

Answer 8

yes

Answer 9

(I'm assuming the $20 membership is a 1-time fee rather than a monthly one, although it's not specified in the question)

Answer 10

67.50 = 2.50x + 20

start by subtracting 20 from both sides, that way all the variables are on one side and all of the constants are on the other

Answer 11

47.5 = -17.5x

Answer 12

remember, if we are only subtracting 20, that shouldn't affect any of the x-terms

Answer 13

2.50x - 20 is not equal to -17.50x because 2.50x and 20 are not like terms

Answer 14

oh 47.5 = 2.50x

Answer 15

good, then you can just divide both sides by 2.50 to isolate x

Answer 16

19 = x

Answer 17
