When , Cost equals Revenue, that is the break-even point. If
you sell 1 more backpack, you will show the smallest profit possible.

Subtract from both sides

to the nearest whole number

and for 160 backpacks which should be positive

If 160 backpacks are sold, the profit will be $33, the smallest possible
