Shelly has $175 to shop for jeans and sweaters. Each pair of jeans costs $25 and each
Ksju [112]

Answer:

3 jeans and 5 sweaters

Step-by-step explanation:

This is a solid guess

However, this is a straight forward question.

175 she has to spend all of it.

To make it an even number you minus 25.

Than you have 150, minus another 50.

You have 5 more clothes to buy, and $100 left.

You use the rest to buy sweaters, therefore spending all the money and getting 8 clothing.
