Answer 1

Answer:
n = 60 shirts
Explanation:
The break-even point is the point where revenue is equal to cost. This means we take the equation for revenue, r = 25n, and set it equal to the equation for cost, c = 10n + 900:
25n = 10n + 900
Subtract 10n from each side:
25n - 10n = 10n + 900 - 10n
15n = 900
Divide both sides by 15:
15n/15 = 900/15
n = 60
