Answer:

He can buy 28 books or less.

Step-by-step explanation:

ox will represent the number of books he can buy. He can only use $230 or less. I am going to use <, but It's supposed to be less than or equal, not less than, so make sure to put a less-than sign with a line under it.

90+5x<230          Subtract 90.

5x<140               Divide by 5.

x<28                    This means that he can buy 28 or fewer/less books.
