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?
30 percent of his inventory is six. Let x=the whole inventory. Then: \[.3x=6\]Divide both sides by .3 to isolate x: \[x=20\]
