Giselle pays $210 in advance on her account at the athletic club. ech time she uses the club,$15 is deducted from the account. model the situation with a linear function.
a. b = 210 + 15x
b. b = 210 – 15x
c. b = 195 + 15x
d. b = 195 – 15x

The linear function model the situation is b = 210 - 15x .

Option (B) is correct .

Step-by-step explanation:

Let us assume that the number of times giselle uses the club be x .

As given

giselle pays $210 in advance on her account at the athletic club.

Each time she uses the club,$15 is deducted from the account.

Let suppose that the money left after giselle uses the club x times is b .

Than the equation becomes

Money left = Amount pay in advance - Deducted amount × Number of times  giselle uses the club .

Put all the values in the above

b = 210 - 15 × x

b = 210 - 15x

Therefore the linear function model the situation is b = 210 - 15x .

Option (B) is correct .
