Found the problem:
Item Cost Sales Price
T-shirt 6 10
hats 4 7
Let x = t-shirts, y = hats
6x + 4y = 2,000
10x + 7y = 3,375
4y = 2000 - 6x
y = 2000/4 - 6x/4
y = 500 - 3x/2
10x + 7y = 3,375
10x + 7(500 - 3x/2) = 3,375
10x + 3500 - 21x/2 = 3,375
10x - 10.5x = 3,375 - 3500
-0.5x = -125
-0.5x / -0.5 = -125/-0.5
x = 250 shirts
They will need 250 shirts.
