## Example Questions

### Example Question #1 : Operations And Algebraic Thinking

Elizabeth is going to buy concert tickets. The concert tickets costs  plus a  sales tax. What is the total price that Elizabeth will pay for her concert tickets?

Explanation:

We know that Elizabeth is going to pay  of the  concert because that is the total cost. Plus, she is going to pay  of the  because that is the sales tax.

First, we need to convert our percentages into decimals in order to multiply.

Next, we can write a numeric expression and solve:

### Example Question #2 : Operations And Algebraic Thinking

Billy makes  a week in allowance plus  for each lawn that he mows. This week Billy wants to make over . Select the inequality for the number of lawns he needs to mow.

Explanation:

We know that Billy needs to make more than  between his allowance and the lawns that he mows. This means our inequality should include

Also, since Billy will make  per lawn, that means we need to multiply  by the number of lawns he needs to mow, :

So far we have the following:

Next, we know that he makes  each week, on top of what he makes mowing each law.

This means we need to add the  to the

When we put all of these pieces together, we will get the following inequality:

### Example Question #3 : Operations And Algebraic Thinking
