__Set up Cost function C(b) where t is the number of tapestries:__

C(b) = Cost per boat * number of boats + Fixed Cost

C(b) = 50b + 1500

__Set up Revenue function R(b) where t is the number of tapestries:__

R(b) = Sale Price * number of boats

R(b) = 75b

__Break even is where Revenue equals Cost, or Revenue minus Cost is 0, so we have:__

R(b) - C(b) = 0

75b - (50b + 1500) = 0

75b - 50b - 1500 = 0

25b - 1500 = 0

To solve for b, we type this equation in our math engine and we get:

b =

**60**
