Respuesta :
For this case, the first thing we must do is define variables.
We have then:
x: number of months
y: total cost
We write the algebraic expression that models the problem:
A gym membership costs $ 25 to join and $ 14 each month.
We have then:
[tex] y = 14x + 25 [/tex]
For 6 months the cost is:
[tex] y = 14 (6) +25 [/tex]
[tex] y = 84 + 25 [/tex]
[tex] y = 109 [/tex]
Answer:
an algebraic expression to find the cost of the gym membership is:
[tex] y = 14x + 25 [/tex]
the cost for 6 months is:
[tex] y = 109 [/tex]
