Answer :

Certainly! Let's solve this math problem step by step.

### Step-by-Step Solution:

1. Understanding the Problem:
- We start with 23 units of money.
- We aim to buy 5 bagels.
- Each bagel costs 3 units of money.

2. Calculating the Total Cost of the Bagels:
- If each bagel costs 3 units of money, and we want to buy 5 bagels, the total cost can be calculated by multiplying the number of bagels by the cost per bagel.
[tex]\[ \text{Total Cost of Bagels} = 5 \, \text{bagels} \times 3 \, \text{units/bagel} = 15 \, \text{units} \][/tex]

3. Calculating the Money Left:
- We started with 23 units of money and spent 15 units on the bagels. To find out how much money is left, we subtract the money spent from the initial amount of money.
[tex]\[ \text{Money Left} = 23 \, \text{units} - 15 \, \text{units} = 8 \, \text{units} \][/tex]

4. Conclusion:
- The amount of money spent on the bagels is 15 units.
- The amount of money remaining after buying the bagels is 8 units.

So, the final answer is the total amount of money spent on the bagels is 15 units, and the amount of money left is 8 units.
