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.
