Sure, let's solve the problem step-by-step.

Question:
Olivia has [tex]$23. She bought five bagels for $[/tex]3 each. How much money does she have left?

Step-By-Step Solution:

1. Initial Amount of Money:
Olivia starts with [tex]$23. 2. Number of Bagels and Cost per Bagel: Olivia buys five bagels. Each bagel costs $[/tex]3.

3. Total Cost of Bagels:
To find out how much Olivia spent on the bagels, we multiply the number of bagels by the cost per bagel.
[tex]\[ \text{Total Cost} = \text{Number of Bagels} \times \text{Cost per Bagel} \][/tex]
Substituting in the values:
[tex]\[ \text{Total Cost} = 5 \times 3 = 15 \][/tex]
So, Olivia spent [tex]$15 on the bagels. 4. Money Left: To find out how much money Olivia has left, we subtract the total cost of the bagels from her initial amount of money. \[ \text{Money Left} = \text{Initial Amount} - \text{Total Cost} \] Substituting in the values: \[ \text{Money Left} = 23 - 15 = 8 \] So, Olivia has $[/tex]8 left after buying the bagels.

Conclusion:
Olivia spent [tex]$15 on the bagels and has $[/tex]8 left.
