A salesperson is paid a base salary of 300 dollars a week plus a 5 percent commission on the sales he generates. Which inequality best represents s , the amount of sales in dollars he must generate to earn more than 500 dollars for the week?

His weekly pay is the $300 base salary plus 5% of sales, so it is 300 + 0.05s. To earn more than $500, solve 300 + 0.05s > 500, which gives 0.05s > 200 and then s > 4,000. The correct choice is “s is greater than 4,000.”
