To solve the sales tax problems, we need to calculate the amount of sales tax each person paid based on the given purchase price and the sales tax rate for their state. The formula to calculate sales tax is:
\[
\text{Sales Tax} = \text{Purchase Price} \times \text{Sales Tax Rate}
\]
Let's solve each problem step by step.

Problem 1: John bought a new couch for $450. Sales tax in his state is 7.75%. How much did he pay in sales tax?
1.
Identify the given values:
- Purchase Price = $450
- Sales Tax Rate = 7.75% = 0.0775 (convert percentage to decimal)
2.
Apply the formula:
\[
\text{Sales Tax} = 450 \times 0.0775
\]
3.
Perform the multiplication:
\[
450 \times 0.0775 = 34.875
\]
4.
Round to the nearest cent (if necessary):
\[
34.875 \approx 34.88
\]
Answer:
\[
\boxed{34.88}
\]

Problem 2: Sara bought a TV for $800. Sales tax in her state is 8.5%. How much did she pay in sales tax?
1.
Identify the given values:
- Purchase Price = $800
- Sales Tax Rate = 8.5% = 0.085 (convert percentage to decimal)
2.
Apply the formula:
\[
\text{Sales Tax} = 800 \times 0.085
\]
3.
Perform the multiplication:
\[
800 \times 0.085 = 68
\]
Answer:
\[
\boxed{68}
\]

Problem 3: Leila bought dinner for $29. Sales tax in her state is 6.05%. How much did she pay in sales tax?
1.
Identify the given values:
- Purchase Price = $29
- Sales Tax Rate = 6.05% = 0.0605 (convert percentage to decimal)
2.
Apply the formula:
\[
\text{Sales Tax} = 29 \times 0.0605
\]
3.
Perform the multiplication:
\[
29 \times 0.0605 = 1.7545
\]
4.
Round to the nearest cent:
\[
1.7545 \approx 1.75
\]
Answer:
\[
\boxed{1.75}
