Answer:
232, 255 dollar sales FPCC need to have at manufacturer's prices before it starts making a profit.
Step-by-step explanation
Lets start with calculation of Variable cost that includes following
Cloth per shirt = 2.2
Button per shirt = 0,05
Thread per shirt = 0.05
Direct labor per shirt = 1.33
Shipping per shirt = 0.27
Adding all these above cost we get per unit varibale cost = 3.9
Manufacturing sales price = 15/140*100 = 10.7
Now calculating sales = 10.7-3.9 = 6.8
Now calculating break even in order to determine point of profitable
Break even = FV/ contribution per unit = 147,600/ 6.8 = 21,706 units
Sales in dollars = 21,706 * 10.7 =232, 255 aprox
