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

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
