A store sold a total of 300 shirts and ties. Ties sold for $15 and shirts sold for $20. Total amount earned was $5375. How many shirts and ties were sold?

Answer 1

S+T = 300

5,375 = 20S + 15T

15S+15T = 4500

subtract last equation from the 2nd

5S = 5375-4500 = 875

S = 875/5 = 175 shirts sold

T = 300-175 = 125 ties sold
