A company makes T-shirts with fixed costs of $600/day and variable cost of $8 per shirt. Shirts sell for $15. How many must be sold daily to earn a profit of $350?

A

120 shirts

B

130 shirts

C

135 shirts

D

140 shirts

Correct Answer: C

Choice C is the correct answer. Let xx = number of shirts.

Profit equation: Revenue - Total Cost = Profit 15x−(600+8x)=35015x - (600 + 8x) = 35015x−600−8x=35015x - 600 - 8x = 3507x=9507x = 950x=9507≈135.7x = \frac{950}{7} \approx 135.7

Rounding down: 135 shirts (can't sell fractional shirts)

💡 Strategic Tip: Profit = Revenue - (Fixed Costs + Variable Costs).
