A new gym opens with 100 members. Each month the membership increases by 20 members. Which equation represents the relationship between the number of months the gym has been opened, x, and the total gym membership, y?(1 point) Responses y=100x+20 y is equal to 100 x plus 20 y=20x+100 y is equal to 20 x plus 100 y=20x y is equal to 20 x y=x+20
y=20x+100
This equation represents the relationship between the number of months the gym has been opened, x, and the total gym membership, y. The initial membership is 100, and each month the membership increases by 20. The constant 100 represents the initial membership level, and the coefficient of x, which is 20, represents the number of new members joining each month.
