Answer: more than 40000
Explanation:
Given : Fixed cost per year = $600,000
Cost of equipment and labor to make one keyboard = $ 10
Selling price of 1 keyboard = $25
Gain on each keyboard = Selling price - cost
= $25 - 410
= $15
Minimum number of keyboards need to sell to make profit = ( Fixed cost) ÷ (Gain)
= 600,000 ÷ 15
= 40000
Hence, Widget Corp. needs to sell more than 40000 keyboards to make profits.
