Answer:
$14.875.
Step-by-step explanation:
We are asked to find the 75% markup of a $8.50 yoga mat.
\(\text{Markup}=\text{Original price}+\text{markup on original price}\)
\(\text{Markup}=\$8.50+\frac{75}{100}*\$8.50\)
\(\text{Markup}=\$8.50+\$6.375\)
\(\text{Markup}=\$14.875\)
Therefore, the price of yoga mat after markup would be $14.875.
