Question

I5. A shirt that you want to buy costs$15.50. You can use a $5 discountcoupon if you spend at least $20.Write and solve an inequality thatrepresents how much more youmust spend to use the $5 coupon.

Answer 1

The shirt costs $15.50. You need to spend at least $20. Calling x to the extra money you need to spend:

15.5 + x ≥ 20

15.5 is adding on the left, then it will subtract on the right

x ≥ 20 - 15.5

x ≥ 4.5

You need to spend extra $4.5
