To calculate the sales tax that Sally will have to pay on her snowblower purchase, you can use the following formula:
\[ \text{Sales Tax} = \text{Price} \times \text{Sales Tax Rate} \]
Given:
- Price = $349.99
- Sales Tax Rate = 7.5% = 0.075
Now, plug in the values:
\[ \text{Sales Tax} = 349.99 \times 0.075 \]
\[ \text{Sales Tax} = 26.24925 \]
Now, rounding this amount to the nearest hundredth:
\[ \text{Sales Tax} \approx 26.25 \]
Thus, Sally will have to pay approximately $26.25 in sales tax.
