How do I write and solve for Jaxon's inequality?

Question

Jaxon needs to order some new supplies for the restaurant where he works. The restaurant needs at least 501 glasses. There are currently 256 glasses. If each set on sale contains 10 glasses, write and solve an inequality which can be used to determine x, the number of sets of glasses Jaxon could buy for the restaurant to have enough glasses.

Answer 1

501-256 = 245 needed

245/10 = 24.5 sets needed

24 sets are not enough, 25 are more than enough

x > (501-256)/10

x > 24.5 sets
