Question

A $120 skateboard is on sale for 15% off and the sales tax is 7.5%. What is the final cost of the skateboard including tax?( make sure you Round to nearest cent)

Answer 1

To find the final cost of the skateboard including tax, follow these steps:

1. Calculate the discount amount:
\[
\text{Discount} = \text{Original Price} \times \text{Discount Rate}
= 120 \times 0.15 = 18
\]

2. Subtract the discount from the original price to find the sale price:
\[
\text{Sale Price} = \text{Original Price} - \text{Discount}
= 120 - 18 = 102
\]

3. Calculate the sales tax on the sale price:
\[
\text{Sales Tax} = \text{Sale Price} \times \text{Sales Tax Rate}
= 102 \times 0.075 = 7.65
\]

4. Add the sales tax to the sale price to find the final cost:
\[
\text{Final Cost} = \text{Sale Price} + \text{Sales Tax}
= 102 + 7.65 = 109.65
\]

Therefore, the final cost of the skateboard including tax is **$109.65**.
