w = 500m + 50c =>50c = w - 500m => c = w/50 - 10m
c = 12100 / 50 - (10*11)
= 242 - 110 = 132 cars sold
Check in original formula
w = (500 * 11) + (50 * 132) = 5500 + 6600 = 12100

a)
50c=w-500m
=>c=w-500m/50
b)
here w=12100,m=11 we have to find c
c=12100-500*11/50 (according to formula obtained above)
c=12100-5500/50
c=132
therefore number of cars =132

a)50c=w-500m
c=(w-500m)/50
b)c=(12100-5500)/50
=6600/50=132 pounds
