Answer 2

x≥13

Explanation:

Hello

I think I can help you with this

step 1

Lets see how much money jon earns per week

$180 (always, it does not depend on the sales)

$25 for each sale=25* sale

$25*number of sales

earning= $180+$25*number of sales

Let

earnings=e

number of sales=x

(1)e=$180+$25x

Step 2

make the inequality

he need to earn at least $500, that is the same that $500 or more ($500.∞)

(2)e≥500

mixing (1) and (2)

$180+$25x ≥$500

x can be isolated

$25x ≥$500-$180

$25x ≥$320

x≥320/25

x≥12.8

he can not make 0.8 sales , so he needs 13 sales or more.(13,∞)

Have a great day
