Lets say the price of a shirt is X, then the price of sweater is X + 3.95

Since a total cost is 71.65 for 3 shirts and 2 sweaters. 71.65 = (3*X) + 2*(X+3.95)

So, 71.65 = 3X + 2X + 7.9

71.65 - 7.9 = 5X

12.75 = X. Therefore, the price of a shirt is 12.75 dollars, and the price of a sweater is 16.7 dollars (12.75 + 3.95)
