Question

A fitness club requires a one time fee of $100 and dues of $10 every month .write an expression for the total cost of membership for n months

Answer 1

cost=100+10n

100 is the Y intercept of the equation because it is a one time thing and not constant. 10 is the coefficient because it is constant and you will have to pay every month.

I know the explanation ain't fantastic but here you go.
