### Detailed Step-by-Step Solution

Let's begin by understanding the problem:

You start with an initial amount of money and buy a certain number of bagels, each at a given cost. The goal is to determine how much money is spent on the bagels and how much money is left after the purchase.

Given:
- Initial amount of money: [tex]\( \$23 \)[/tex]
- Number of bagels bought: [tex]\( 5 \)[/tex]
- Cost per bagel: [tex]\( \$3 \)[/tex]

#### Step 1: Calculate the Total Money Spent on Bagels

To find out how much money is spent on the bagels, multiply the number of bagels by the cost per bagel.

[tex]\[ \text{Money Spent} = \text{Number of Bagels} \times \text{Cost per Bagel} \][/tex]

Substitute the given values into the formula:

[tex]\[ \text{Money Spent} = 5 \text{ bagels} \times \$3 \text{ per bagel} \][/tex]
[tex]\[ \text{Money Spent} = \$15 \][/tex]

So, the total money spent on bagels is \[tex]$15. #### Step 2: Calculate the Remaining Money Now, we need to figure out how much money is left after buying the bagels. Subtract the total money spent from the initial amount of money. \[ \text{Money Left} = \text{Initial Money} - \text{Money Spent} \] Substitute the given values into the formula: \[ \text{Money Left} = \$[/tex]23 - \[tex]$15 \] \[ \text{Money Left} = \$[/tex]8 \]

So, the amount of money left after buying the bagels is \[tex]$8. ### Conclusion - The total money spent on bagels is \$[/tex]15.
- The amount of money left after the purchase is \$8.

These are the final results of the calculations.
