15(7.5) = Original price

and found the regular price of the camera to be $112.50.

Answer:

The original price is $50

see the explanation

Step-by-step explanation:

we know that

$7.50 represent a percentage of 15%

so

using proportion

Find out how much represent a percentage of 100% (original price)

Let

x -----> the original price    

\(\frac{\$7.50}{15\%}=\frac{x}{100\%}\\\\x=100(7.50)/15\\\\x=\$50\)

therefore

The student should have divided the discounted amount by the percent. The percent should have been written as a decimal
