Sarah bought T-shirts and hats on sale. The T-shirts cost $12 each, and the hats cost $9 each. She bought 4 more T-shirts than hats. If she spent a total of $111, how many T-shirts and hats did she buy?

12t + 9h = 111
t = h + 4

12(h + 4) + 9h = 111
distribute the 12

12h + 48 + 9h = 111
Combine like terms

21h + 48 = 111
Subtract 48 from both sides

21h = 63
Divide both sides by 21

h = 3
t = 7

CHECK: 3(9) + 7(12) =
27 + 84 =
$111
