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.
