Step-by-step explanation:

Let's recall the formula of the break-even point:

Revenue - Cost = 0

Revenue = Cost

Replacing with the information we know, for solving for x:

120x = 100x + 1,840

120x - 100x = 1,840

20x = 1,840

x = 1,840/20

x = 92

If the company needs to sell at least 92 guitars to reach the break-even point, selling 93 will allow them to start making a profit.

r(93) = 120 * 93 = 11,160

c(93) = 100 * 93 + 1,840 = 11,140

Profit = 11,160 - 11,140 = 20
