.A salesperson is paid $10 per week plus $8 per sale. This week, the salesperson wants to earn at least $250. Which inequality represents the number of sales, s, the salesperson must make in order to meet that goal?

Given:

A salesperson is paid $10 per week plus $8 per sale.

This week, the salesperson wants to earn at least $250.

To find:

The inequality represents the number of sales, s, the salesperson must make in order to meet that goal.

Solution:

Let s be the number of sales.

Fixed earnings = $10 per week

Earning on 1 sale = $8

Earnings on s sales = $8s

Total earnings = Fixed earnings + Additional earnings of sale

This week, the salesperson wants to earn at least $250. It means, total earning must be greater than or equal to 250.

Divide both sides by 8.

Therefore, the inequality represents the number of sales, s, the salesperson must make in order to meet that goal.
