Solve each problem.

Warehouse Club Membership Suppose that the annual fee for a warehouse club membership is $50 and that the reward rate on club purchases for the year is 1.6%. Then the actual annual cost of a membership y, in dollars, for an amount of annual club purchases x, in dollars, can be modeled by the following linear equation. y = 50 - 0.016x

(a) Determine the actual annual cost of the membership if club purchases for the year are $1500.

(b) What amount of club purchases would reduce the actual annual cost of the membership to $0?

(c) If club purchases for the year exceed $3125, how is the actual annual membership cost affected?
