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

b = 210 - 15x
Explanation:
Let b be the balance remaining on Giselle's account after she uses the club x times. Initially she paid $210 in advance, so the starting balance is $210. Each time she uses the club, $15 is deducted from her account, hence the term -15x. So the linear function representing this situation is b = 210 - 15x.
