To calculate the sales tax, you can use the 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:
\[ \text{Sales Tax} = 349.99 \times 0.075 \]
Calculating this gives:
\[ \text{Sales Tax} = 26.24925 \]
Now, round this to the nearest hundredth:
\[ \text{Sales Tax} \approx 26.25 \]
So, Sally will have to pay $26.25 in sales tax.
