Question

Full:

Mr. Hong has coins and old stamps for sale. He decides to advertise the items on an internet site for collectors. It will cost him $84 initially to advertise and $28 for each day he keeps the items on sale. If you Mr. Hong does not want to spend more than $700 advertising, what is the maximum number of days he should advertise? Write and solve an inequality to answer the question.

Can you please help me?

Answer 1

Write your inequality by following what the problem says.

84 (the initial price)

28x (28 dollars times the number of days)

700 (the most he wants to spend

84+28x<700

Then solve for x. Subtract 84 from both sides, then divide both sides by 28.
