A game store has 150 Xbox's. If the store owner decides to increase his inventory by 17%, how many more Xbox's does he need to buy?

I don't understand this question or how to solve it. I tried to put it as a proportion but it didn't seem right. Please help!!!

I assume one cannot buy a half of an Xbox, so he would need to buy 26.

When it comes to word problems the word "of" should always translate to "multiply" in your head.
3 sets of 2 is 3(2) = 6...  17% of 150 means multiply so 17%(150) = (17/100)(150) = 25.5 as Mark said.

Reconsidering my response: He needs to buy 150 + 26 or 176 Xboxes for inventory.
