Certainly! Let's break down and explain a similar question step-by-step for clarity.

Question: Olivia has [tex]$23. She bought five bagels for $[/tex]3 each. How much money does she have left?

Solution:

1. Initial amount of money: Olivia starts with [tex]$23. This is the initial amount of money she has. 2. Cost of one bagel: Each bagel costs $[/tex]3.

3. Number of bagels bought: Olivia buys five bagels.

4. Total cost of bagels: To find out how much Olivia spends on the bagels, you need to multiply the cost of one bagel by the number of bagels bought.
[tex]\[ \text{Total cost} = \text{Number of bagels} \times \text{Cost per bagel} = 5 \times 3 = 15 \][/tex]

5. Money left: To find out how much money Olivia has left after buying the bagels, you subtract the total cost of the bagels from her initial amount of money.
[tex]\[ \text{Money left} = \text{Initial amount} - \text{Total cost} = 23 - 15 = 8 \][/tex]

So, after buying the bagels, Olivia has [tex]$8 left. To summarize: - Olivia initially had $[/tex]23.
- She spent [tex]$15 on five bagels. - She has $[/tex]8 left after the purchase.

These steps ensure we methodically approached the problem and arrived at the correct answer of $8 remaining.
