Answer :

Sure! Let's go through this problem step-by-step:

Olivia starts with an initial amount of money. Here's how we can determine how much money she will have left after buying some bagels:

1. Initial Amount of Money:
Olivia initially has [tex]$23. 2. Cost per Bagel and Number of Bagels: Each bagel costs $[/tex]3, and she buys 5 bagels.

3. Amount of Money Spent on Bagels:
To find out how much money she spent, we need to multiply the cost per bagel by the number of bagels she bought:

[tex]\( \text{Amount Spent} = 5 \text{ bagels} \times \$ 3 \text{ per bagel} = \$ 15 \)[/tex]

4. Amount of Money Left:
To find out how much money Olivia has left, we subtract the amount she spent on bagels from her initial amount of money:

[tex]\( \text{Amount Left} = \$ 23 - \$ 15 = \$ 8 \)[/tex]

So, by following these steps:

- Olivia spent [tex]$15 on bagels. - She has $[/tex]8 left after buying the bagels.

The detailed solution gives us two key numbers for the question:

1. Amount of money spent on bagels: [tex]$15 2. Amount of money left: $[/tex]8
