Answer
$44
Work Step by Step
The discount on the dictionary’s price is 30%. So, the percentage of the original price at which it was bought is
$100-30=70%$
Consider the equation to calculate the price at 70%
$x\times \frac{70}{100}=30.80$
Here, x is the price before reduction.
Now, solve the above equation
$\begin{align}
& x\times \frac{70}{100}=30.80 \\
& x=30.80\times \frac{100}{70} \\
& =\$44\end{align}$
Thus, the dictionary’s price before reduction was $44.
