Let's solve the question systematically:
1. Money Spent on Bagels:
- Each bagel costs 3 units.
- The number of bagels purchased is 5.
- To find the total money spent on bagels, multiply the cost per bagel by the number of bagels.
[tex]\[
\text{Money spent on bagels} = \text{Cost per bagel} \times \text{Number of bagels} = 3 \times 5 = 15
\][/tex]
2. Money Left:
- The initial amount of money was 23 units.
- Subtract the money spent on bagels from the initial amount to find out how much money is left.
[tex]\[
\text{Money left} = \text{Initial money} - \text{Money spent} = 23 - 15 = 8
\][/tex]
Therefore, the amount of money spent on bagels is 15 units, and the money left is 8 units.
