Giselle pays $220 in advance on her account at the athletic club. each time she uses the club,
$15 is deducted from the account. write a linear function to model the situation. define what
each of your variables represents.

Step-by-step explanation:

Let x represent the number of times Giselle uses the athletic club and y represent money left in account.

We have been given that each time she uses the club,  $15 is deducted from the account. The amount used after using the club after x times would be .

We are also told that Giselle pays $220 in advance on her account at the athletic club.

The money left in account after x uses of athletic club would be money in account initially minus amount used for using the club x times.

Therefore, our required equation would be .

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
