Question

Today only, a desk is being sold at a 35% discount. The sale price is $429.What was the price yesterday?

Answer 1

Given:

The discount for the desk today, D=35%.

The sale price, SP=$429.

The expression for sale price is,

$SP=\frac{100-D}{100}\times CP$

Here, CP is the price yesterday.

Substitute the known values and solve for CP.

$\begin{gathered} 429=\frac{100-35}{100}\times CP \\ 429=\frac{65}{100}\times CP \\ CP=\frac{429\times100}{65} \\ CP=660 \end{gathered}$

Therefore, the price yesterday is $660.
