Rich · Answer 1

A) let x=months let y=cost y=mx+b y = 20x + 60 Remember 20 is the variable which implies for this situation consistently it cost 20$ and 60 is the steady which implies you just pay it once

B) let x = Months let y = cost y=10x + 150

C) platinum rec center y = 20x+60 y=20 (1) + 60 y=20+60 y=80 Superfit y=10x+150 y=10 (1) + 150 y=10+150 y=160 Therefore Tom will pay less after the main month
