Question 1178475: 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 - 0.016 x
(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?

Hi
y = 50 - 0.016x
a) y = $50 - 0.016 (1500) = $26
b) 0 = $50 - 0.016x 
 x = $50/.016 = $3125
c) If club purchases for the year exceed $3125, how is the actual annual membership cost affected? 
after membership fee has been totally credited, might suspect a cash
refund of any remaining reward credit would be given.
Wish You the Best in your Studies.
