Question

Chantal would like to buy a new pair of running shoes. shoes that she likes start at 62$, what is the least amount she must spend?

A: write an inequality and solve

b: graph

Answer 1

Hi there! I can help you! An inequality does not involve just an equal sign. It helps us get a clearer picture of the ranges of the amount that work in different situations. In this case, out inequality would be this:

62 + x ≥ 85

We are looking for how much more money needs to be saved. it could be right at that amount or equal to, so we use the greater than or equal to symbol. 62 is what we already have, so we put that amount in the expression as well. We are doing this to find the amount away from 85.

How to solve it:

Okay. So first things first, we will subtract 62 from both sides. 62 - 62 cancels out. 85 - 62 is 23. That's it! x ≥ 23. At least, Chantel will need to save $23 more in order to buy the pair of shoes she wants.
