Question

A car salesperson has already sold 30 cars this year. He sells an average of 13 cars per month. Write an inequality to determine how many months, m, it will take for him to sell more than 60 cars.

Answer 1

Explanation:

We can use the inequality m * 13 > 60, where m is the number of months and 13 is the average number of cars sold per month. To solve for m, we can divide both sides of the inequality by 13: m > 60/13. This inequality tells us that it will take more than 4.6 months for the salesperson to sell more than 60 cars.

However, since m is a number of months, it is an integer. We need to round up this value, to ensure that the inequality is satisfied.

So the answer is m > 5 months.
