Break even occurs when costs = revenues. This means the same amount of money spent on the baskets is the same as the money people spent on the baskets.
I don't see a question here but I am going to assume that the question is how many baskets must be sold to break even - ? If so, then set C = R and solve for x. Remember that you cannot sell a portion of a basket, so if x is any decimal, then round up (even if the decimal is would not normally round up).
10x + 713 = 33x
