Answer :

Let's carefully go through the given question and its final result to provide a detailed, step-by-step solution.

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

Solution Steps:

1. Identify Initial Amount of Money:
- Olivia has [tex]$23 initially. 2. Identify Cost and Quantity of Bagels: - Each bagel costs $[/tex]3.
- Olivia bought five bagels.

3. Calculate Total Expenditure on Bagels:
- Since bagels cost [tex]$3 each and she bought five, the total amount spent on bagels is: \[ \text{Total cost of bagels} = \text{Number of bagels} \times \text{Cost per bagel} \] \[ \text{Total cost of bagels} = 5 \, \text{bagels} \times 3 \, \text{dollars/bagel} = 15 \, \text{dollars} \] 4. Calculate Remaining Money: - Subtract the total cost of bagels from the initial amount of money: \[ \text{Money left} = \text{Initial amount} - \text{Total cost of bagels} \] \[ \text{Money left} = 23 \, \text{dollars} - 15 \, \text{dollars} = 8 \, \text{dollars} \] Final Result: - Amount of Money Spent on Bagels: $[/tex]15
- Amount of Money Left: [tex]$8 Thus, after purchasing the bagels, Olivia has $[/tex]8 left.
