Question

Hillary earns $60 per week at her job, plus $2 for each item she sells. She wants to

earn at least $300 per week. Write an inequality to represent how many items, x, Hilary
must sell.

Answer 1

120 items

Explanation:

60+2x=300

-60. -60

2x=240

2. 2

x=120

Answer 2

60+2x≥300

Explanation:

So we know that she makes a base of $60 a week and gets $2 extra for every item she sells. First, we set up an equation for how many items she would have to sell to make exactly $300 in a week. 60+2x=300. Now, all we do is replace the equal sign with a ≥ sign because it says at least which means more than or equal to.
