You can put this solution on YOUR website! 2) c=15b+125,
1) r=40b,
3)c=r,
4) backpacks b = 5, cost c = 200, revenue r = 200
5)p=r-c
6)p=r-c
c=15b+125,
r=40b,
b=60
backpacks b = 60, cost c = 1025, profit p = 1375, revenue r = 2400
7)p=3625
p =r-c
c=15b+125,
r=40b
backpacks b = 150, cost c = 2375, profit p = 3625, revenue r = 6000
