To date, this year, Company XYZ has sold 600 units. They sell units at an average rate of 20 per week. The company wants to sell more than 1,000 units this year. Which of the following inequalities could be used to solve for x, the number of weeks necessary to reach the company's year-end goal?
Let x be the number of weeks necessary to reach the company's year-end goal.
Since they sell units at an average rate of 20 per week, the number of units sold after x weeks would be 20x.
To reach the company's year-end goal of selling more than 1,000 units, the inequality 20x > 1,000 can be used to solve for x.
