A fitness club opens with 90 members. Each month the membership increases by 15 members. Which equation represents the relationship between the number of months the club has been opened, x, and the total fitness club membership, y?

• y=15x

• y=15x+90

Write an equation: The total cost of renting a car is $65 for deposit and $37.50 per day.

• x = 65 + 37.50 y

• y = 65 x + 37.50

• y= 92.50x

• y= 37.50 x + 65
