You can put this solution on YOUR website! Here's how to break down the inequalities:
**1. Inequality describing the possible retail value of items:**
Let 'x' represent the retail value of the items you buy. To use the coupon, the retail value must be $50 or more. So:
x ≥ 50
**2. Inequality describing the different amounts of money you can spend:**
Let 'y' represent the amount of money you actually spend after using the coupon. Since you have $60 and the coupon takes $10 off, the most you can spend is $60, and the least you can spend is $40 ($50 - $10).
y ≤ 60
y ≥ 40
Combining these, the inequality that describes the different amounts of money you can spend is:
40 ≤ y ≤ 60

~~~~~~~~~~~~~~~~~~~~~~~~
The inequality for the retail value of items, which you can buy,
having $60 in your pocket, when you use a coupon, is
50 <= r <= 70.
The inequality for the amount of money you can spend, having $60 in your pocket,
when you use a coupon is
40 <= y <= 60.
Solved.

You can put this solution on YOUR website! Merchandise can be chosen up to $70. No more than $70.
The coupon starts only at a minimum of merchandise worth $50.
"you" may only have $60, but can pick merchandise of greater retail value than 60 because you have the $10 coupon.
