To calculate the sale price of the exercise machine after a 9% markdown, follow these steps:
-
Calculate the amount of the markdown:
\[ \text{Markdown} = \text{Original Price} \times \frac{\text{Markdown Percentage}}{100} \] \[ \text{Markdown} = 790 \times \frac{9}{100} = 790 \times 0.09 = 71.10 \]
-
Subtract the markdown from the original price:
\[ \text{Sale Price} = \text{Original Price} - \text{Markdown} \] \[ \text{Sale Price} = 790 - 71.10 = 718.90 \]
Therefore, the sale price of the exercise machine is $718.90.
