Question

An item is worth $240 now. This is after a 70% decrease in value. What was its original worth?

Answer 1

SOLUTION

An item is worth $240 now

This is after a 70% decrease

Let the Original worth = P

$100-70=30$

Therefore

$\begin{gathered} 30\text{ \% of P=240} \\ 0.3P=240 \\ p=\frac{240}{0.3} \\ p=800 \end{gathered}$

Therefore the original worth = $800
