Answer:
24 t shirts
Step-by-step explanation:
revenue - expenses = profit
profit = $71
expenses = $25
revenue = money made from t shirts = $4 for each t shirt, x times (she makes $4 for each t shirt and sells x t shirts) = $4 * x
4 * x - 25 = 71
add 25 to both sides to isolate the variable and its coefficient
4x = 96
divide both sides by 6 to isolate x
x = 24
