Question

Tyree sold t-shirts for a Math Club fundraiser. During the first week, he sold 6 t-shirts, which was thirty percent of his inventory. How many t-shirts were in his inventory?

Answer 1

30% of what = 6
.30x = 6
x = 6/.30
x = 20

70% of 20 = x
(.70)(20) = x
14 = x

6 t-shirts = 30%
14 t-shirts = 70%
for a total of 20 t-shirts = 100%
