Answer :

Certainly, let's break down the solution to the given math problem.

Problem Statement:
You start with [tex]$23. You want to buy 5 bagels, and each bagel costs $[/tex]3. The questions are:
1. How much money do you spend in total on bagels?
2. How much money do you have left after buying the bagels?

Step-by-Step Solution:

1. Initial Amount of Money:
- You start with [tex]$23. 2. Cost per Bagel: - Each bagel costs $[/tex]3.

3. Number of Bagels:
- You want to buy 5 bagels.

4. Total Money Spent on Bagels:
- To find the total amount of money spent on bagels, multiply the number of bagels by the cost per bagel. This is calculated as:
[tex]\[ \text{Total Money Spent} = \text{Number of Bagels} \times \text{Cost per Bagel} = 5 \times 3 = 15 \][/tex]

5. Money Left After Buying Bagels:
- Subtract the total money spent from the initial amount of money to find out how much money you have left. This is calculated as:
[tex]\[ \text{Money Left} = \text{Initial Amount of Money} - \text{Total Money Spent} = 23 - 15 = 8 \][/tex]

Answers:
1. The total money spent on bagels is [tex]$15. 2. The money left after buying the bagels is $[/tex]8.

So, you have spent [tex]$15 on bagels and have $[/tex]8 remaining.
