Let's solve the problem using the principles of arithmetic and algebra.
1. Identify the given amounts:
- Initial amount of money: 23 units.
- Number of bagels to be bought: 5.
- Cost per bagel: 3 units.
2. Calculate the total cost of the bagels:
- To find the total amount of money spent on bagels, multiply the number of bagels by the cost per bagel:
[tex]\[
\text{Money spent} = \text{Number of bagels} \times \text{Cost per bagel}
\][/tex]
Therefore:
[tex]\[
\text{Money spent} = 5 \times 3 = 15 \text{ units}
\][/tex]
3. Determine the remaining amount of money:
- Subtract the total cost of the bagels from the initial amount of money to find out how much money is left:
[tex]\[
\text{Money left} = \text{Initial money} - \text{Money spent}
\][/tex]
Therefore:
[tex]\[
\text{Money left} = 23 - 15 = 8 \text{ units}
\][/tex]
4. Summary of the results:
- The total money spent on bagels is 15 units.
- The amount of money left after the purchase is 8 units.
The final answers are:
- Money spent: 15 units
- Money left: 8 units
