Answer:
Step-by-step explanation:
a)
eq 1) 97.50 = fee + 10x
eq 2) 83.50=fee +8x
subtract eq 2 from eq 1
14 = 2x
7 =x
each visit costs $7
b)
97.50 = fee + 10(7)
97.5- = fee +70
27.5 = fee
it costs $27.50 to sign up at the gym
( this seems like an expensive gym )
c)
gym costs = 27.50 + 7 per visit
cost = 27.50 +7x
( let's look for a less expensive gym :D )
