To find the price after the discount, find at first, the amount of discount then subtract it from the original price
Since the discount is 10% of $75, then
Change 10% to decimal by divide it by 100, then multiply it by 75
[tex]\begin{gathered} \frac{10}{100}\times75=0.1\times75 \\ =7.5 \end{gathered}[/tex]The discount is $7.5
Subtract it from $75 to find the price after the discount
The price after discount = 75 - 7.5 = 67.5
The price after the discount is $67.5
