Question

a fitness club opens up with 80 members. Each month the membership increases by 15 members. Which equation represents the relationship between the number of months the club has opened, x, and the total club membership,y?

Answer 1

15x+80=m

Explanation:

where x is the number of months and m is the amount of members

Answer 2

Answer/Step-by-step explanation:

y = 15x + 80

The club start with 80. Then each month 15 people are added so the slope is 15. So replace m in the equation y = mx + b with 15.

Next, replace the variable b of y = 15x +b with 80. because the original 80 members is a one time thing that stays there.

Now you have the equation y = 15x + 80. Which correctly describes the fitness club's situation.
