Question

thepriceof a microwaveoven was marked downfrom $187.50 to $150.00what was the percentdecrease in price.

Answer 1

Let us get the difference in the price of the microwave oven

`\begin{gathered} price\text{ difference=\$187.50-\$150.00} \\ \text{price difference=\$37.50} \end{gathered}`

Let us get the percentage decrease in price

`\begin{gathered} \frac{\text{price difference}}{Actual\text{ price}}*100\text{ \%} \\ \\ \text{where Actual price=\$187.50} \end{gathered}`
`\begin{gathered} \text{ }\frac{\text{\$37.50}}{\text{ \$187.50}}*100\text{ \%} \\ =\frac{3750\text{ \%}}{187.50}=20\text{ \%} \end{gathered}`

Hence, the percentage decrease is 20%.
