Sagot :

Certainly, let's break down the steps to understanding the given problem and its numerical results:

### Problem Description

You start with [tex]$23. You plan to buy some bagels. Each bagel costs $[/tex]3. You decide to buy 5 bagels. We need to determine:

1. How much money is spent on the bagels.
2. How much money you have left after buying the bagels.

### Steps to the Solution:

1. Identify Initial Conditions:
- Initial money: [tex]$23 - Number of bagels you want to buy: 5 - Price per bagel: $[/tex]3

2. Calculate Money Spent on Bagels:
- To find out how much money you spend on bagels, you multiply the number of bagels by the cost of each bagel.
- Money spent = Number of bagels × Cost per bagel
- Money spent = 5 × 3
- Money spent = [tex]$15 - Therefore, the total amount spent on bagels is $[/tex]15.

3. Calculate Remaining Money:
- To find out how much money you have left, subtract the money spent from the initial amount of money.
- Money left = Initial money - Money spent
- Money left = 23 - 15
- Money left = [tex]$8 - Therefore, the money left after buying the bagels is $[/tex]8.

### Summary:

1. The total amount of money spent on bagels is [tex]$15. 2. The amount of money left after purchasing the bagels is $[/tex]8.

These calculations help you manage your money efficiently, ensuring that you know exactly how much you can spend and how much will remain after your purchases.
