To determine how much money Olivia has left after buying bagels, let's go through the steps of solving the problem:

1. Initial Amount: Olivia starts with an initial amount of [tex]$23. 2. Cost of Each Bagel: Each bagel costs $[/tex]3.
3. Number of Bagels: Olivia buys 5 bagels.

To find out how much Olivia spent on the bagels:
- Multiply the number of bagels by the cost per bagel:
[tex]\[ 5 \text{ bagels} \times 3 \text{ dollars per bagel} = 15 \text{ dollars} \][/tex]

This means Olivia spent [tex]$15 on bagels. To find out how much money Olivia has left: - Subtract the amount spent from the initial amount: \[ 23 \text{ dollars (initial)} - 15 \text{ dollars (spent)} = 8 \text{ dollars (left)} \] Therefore, Olivia has $[/tex]8 left after buying the bagels.

In summary:
- Money spent on bagels: [tex]$15 - Money left after purchase: $[/tex]8
