Sagot :

Let's break down the question step by step as a structured math problem.

We begin with an initial scenario that relates to Simen's financial situation:

1. Initial Amount of Money:
Simen initially has 23 units of money.

2. Number of Bagels Purchased:
Simen buys 5 bagels.

3. Cost per Bagel:
Each bagel costs 3 units of money.

### Detailed Steps:

Step 1: Calculate the Money Spent on Bagels

First, we need to determine how much money Simen spends on the bagels. We do this by multiplying the number of bagels by the cost per bagel.

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

Given:
- Number of Bagels = 5
- Cost per Bagel = 3

Substitute these values into the equation:

[tex]\[ \text{Money Spent} = 5 \times 3 = 15 \][/tex]

So, Simen spends 15 units of money on the bagels.

Step 2: Calculate the Money Left

Next, we need to find out how much money Simen has left after buying the bagels. We do this by subtracting the money spent from the initial amount of money.

[tex]\[ \text{Money Left} = \text{Initial Money} - \text{Money Spent} \][/tex]

Given:
- Initial Money = 23
- Money Spent = 15

Substitute these values into the equation:

[tex]\[ \text{Money Left} = 23 - 15 = 8 \][/tex]

So, after purchasing the bagels, Simen has 8 units of money left.

### Summary:

- Money Spent on Bagels: 15 units
- Money Left: 8 units

Therefore, the final results are:
[tex]\[ \boxed{15 \text{ units spent, and 8 units left.}} \][/tex]
