Answer:
D
Step-by-step explanation:
Contribution margin is the level of output at which revenue would equal zero
Contribution margin = fixed cost / (price - variable cost)
fixed cost = 1000 + 300 = 1300
variable cost :
t shirt = 6 + 2 = 8
sweats = 10 + 2 -= 12
1300 / ( 15 - 8) = 185.71
1300 / ( 25 - 12)
