Richard spent over $220 at an office supply store. he bought x reams of paper for $9 each and eight boxes of pens for $5 each. model richard's situation with an inequality, and solve for x. what can be interpreted about the solution of the inequality?

We are given

Richard spent over $220 at an office supply store

so, total money spent over =$220

He bought x reams of paper for $9 each

So, money spent on paper is

eight boxes of pens for $5 each

so, money spent on pens is

now, we can find total money spent

so, total money spent is

now, we are given maximum money he can spent over $220

we get

So, inequality is

now, we can solve for x

Subtract both sides by 40

Divide both sides by 9

Interpretation:

Since, x is the number of reams of paper

so, he can buy more than  20 reams of paper...........Answer
