To calculate the sales tax, you multiply the price of the snowblower by the sales tax rate.
The formula for sales tax is:
\[ \text{Sales Tax} = \text{Price} \times \text{Tax Rate} \]
In this case, the price is $349.99 and the tax rate is 7.5% (which can be written as 0.075).
Now, calculate the sales tax:
\[ \text{Sales Tax} = 349.99 \times 0.075 = 26.24925 \]
Rounding to the nearest whole dollar, Sally will pay $26 in sales tax.
If you meant to round it to the nearest hundred, it would be $0, because $26 rounded to the nearest hundred is $0.
