Sagot :

Let's address the given question step-by-step with the necessary calculations and explanations.

Firstly, the problem involves the initial amount of money, amount spent on bagels, and the remaining money.

### Step-by-Step Solution:

1. Initialization:
- You start with an initial amount of [tex]\( \$23 \)[/tex].

2. Cost of Bagels:
- Each bagel costs [tex]\( \$3 \)[/tex].
- You buy [tex]\( 5 \)[/tex] bagels.

3. Calculate Total Money Spent on Bagels:
- The total cost of the bagels is calculated by multiplying the number of bagels by the cost per bagel:
[tex]\[ \text{money spent} = 5 \times 3 = 15 \][/tex]
- Therefore, the total money spent on bagels is [tex]\( \$15 \)[/tex].

4. Calculate Remaining Money:
- To find out how much money you have left, subtract the money spent from the initial amount of money:
[tex]\[ \text{money left} = 23 - 15 = 8 \][/tex]
- Therefore, the remaining money after buying the bagels is [tex]\( \$8 \)[/tex].

### Summary of Results:

- Money Spent on Bagels: [tex]\( \$15 \)[/tex]
- Money Left: [tex]\( \$8 \)[/tex]

Hence, by following this sequence of calculations, we determine that you spent [tex]\( \$15 \)[/tex] on bagels and had [tex]\( \$8 \)[/tex] remaining.
