Given:
The price of a cell phone was marked down by $35.
The original price of the cell phone was $212.
To find:
The percentage rate of the discount.
Solution:
We have,
Price marked down by= $35
Original price = $212
Now, the percentage rate of the discount is
[tex]Discount\%=\dfrac{\text{Price marked down by}}{\text{Original price}}\times 100[/tex]
[tex]Discount\%=\dfrac{35}{212}\times 100[/tex]
[tex]Discount\%=\dfrac{3500}{212}[/tex]
[tex]Discount\%=16.509434[/tex]
[tex]Discount\%\approx 16.51[/tex]
Therefore, the rate of discount in percentage is 16.51%.
