Question

Giselle pays $240 in advance on her account at the athletic club. Each time she uses the club, $5 is deducted from the account. Model the situation with a linear function?

b = 240 + 5x

b = 235 – 5x

b = 240 – 5x

b = 235 + 5x

Answer 1

I believe the answer is b=240-5.

Answer 2

Option C. is the correct option.

Explanation:

Giselle pays $240 in advance on her account at the athletic club.

Each time she uses the club, $5 is deducted from the account.

Let x be the number Giselle used the club then amount deducted from the account will be = 5x

If b is the balance showing in her account after deduction then this situation can be modeled as

b = 240 - 5x

Therefore option C. b = 240 - 5x is the answer.
