Mary is a sales associate in a clothing store. Each week she earns $250 plus a commission equal to 3% of her sales. This week her goal is to earn no less than $460. Write an inequality to find the dollar amount of the sales she must have to reach her goal.

Question

anonymous · Answer

460-250=210 She has to earn at least $210 from sales. As what she gets is 3% of what she sells, $210 is 3% of her sales, therefore $70 is 1%. This makes $7000 (which is 100 percent) the minimum amount of sales she has to make. Therefore, $$Her sales \ge $7000$$
