A personal workout gym offers its customers $11 every month and an additional fee of $9 for maintenance. Write an expression to represent the monthly plan to workout at this gym. How much will customers have to pay after 4 months?

$80

Step-by-step explanation:

First I'll ask (cause I'm not an expert at english)(and I'm a child)

Additional fee for maintenance is a thing you pay every month right?

In that case,

Monthly fee per month (m): 11

Additional fee per month (a): 9

Total fee per month (t): [m+a] or [11+9]

Total fee for 4 months (x): (11+9)x4=80

Customers will have to pay $80 after 4 months.

20m = t

$80.00

Step-by-step explanation:

Every month is $11, however, there is an additional fee of $9 every month for maintenance. So, 11 + 9 = 20. The gym charges $20 per a month.

Let m be the amount of months and t be the total amount of money charged for m.

20m = t

If m = 4, then 20*4 = 80

T = 80

So, customers would have to pay $80 after 4 months.

Hope this helps :)
