Answer 1

the person above me is correct

Answer 2

We can find the number of months for the total cost of each fitness center to be equal from the following equation:
80n = 75 + 55n
where n is the number of months.
The solution to this equation is n= 3 months.
Therefore answer choice d is correct, "it appears that if you attend the center for less than 3 months, fit-n-trim offers the lower rate. if you attend for more than 3 months, fit-for-life offers the better rate."
