To determine how much change Pia should receive, let's follow these steps:
1. Identify the items ordered and their costs:
- Pia ordered a salad which costs [tex]$7.00.
- Pia also ordered a drink which costs $[/tex]2.50.
2. Calculate the total cost of the ordered items:
- The cost of the salad is \[tex]$7.00.
- The cost of the drink is \$[/tex]2.50.
- To find the total cost, add these amounts together:
[tex]\[
\text{Total cost} = 7.00 + 2.50 = 9.50
\][/tex]
3. Determine the amount paid by Pia:
- Pia paid with a \[tex]$20.00 bill.
4. Calculate the change Pia should receive:
- To find the change, subtract the total cost from the amount paid:
\[
\text{Change} = 20.00 - 9.50 = 10.50
\]
Thus, the total cost of Pia’s order is \$[/tex]9.50, and the change she should receive is $10.50.
