Okay, to start, we can multiply the $2 coupon by two because that is the amount of pairs she is going to by. So it would be $4 off. Now, if all of the shoes she purchased the same price, this is made a little easier. We can simply take $80 and $122 and add it by the $4 discount. Our new numbers would be $84 and $126. Now in order for this to work we would want all the numbers to be the same. We take $84 and divide it by three pairs, to get the values. For the least amount she can spend per pair is $28 and the most amount she can spend per pair is $42.
Answer:
Lest amount : $28
Most amount : $42
Step-by-step explanation:
Hi, to answer this question we have to write an inequality using the information given:
- Shelly is willing to spend $80 to $122
- She will buy 3 pairs of shoes
- She has a coupon for $2 off per pair of shoes after buying the first pair for full price
So, without the coupon the inequality is:
80 ≤ 3x ≤122
Where x is the price of each pair of shoes.(multiplied by 3 because she wants to buy 3 pairs)
Since she has a $2 off coupon per pair after the first, we can say that she has $4 added to her budget ( $2 x 2 pairs ).
So the final inequality is
84 ≤ 3x ≤126
Solving:
84/3 ≤ x ≤126/3
28 ≤ x ≤42
Least amount: $28
Most amount: $42
