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.

A: b = 235 + 5x

B: b = 240 - 5x

C: b = 235 - 5x

D: b = 240 + 5x

Giselle pays $240 on advance

Each time she uses,$5 is deducted

Let no of time she use be x

So, Amount deducted = 5x

As Giselle pays $240 in advance

So 5x amount will be deducted from $240 to get net amount

So b = 240-5x

B) is Correct

B) b = 240 - 5 x is the required expression to decipher the situation.

Step-by-step explanation:

The amount paid to the club in the advance = $240

Amount deducted in each visit = $5

Let us assume the number of times the club visited = x

So, the amount deducted in x visits = x ($5) = 5x

Let b : amount Left after x visits

So, Amount left after x visits = Advance Amount - Deductions after x visits

⇒ b = $240 - 5x

or, b = 240 - 5x is the required expression to decipher the situation.
