Given:

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

The sale price, SP=$429.

The expression for sale price is,

[tex]SP=\frac{100-D}{100}\times CP[/tex]

Here, CP is the price yesterday.

Substitute the known values and solve for CP.

[tex]\begin{gathered} 429=\frac{100-35}{100}\times CP \\ 429=\frac{65}{100}\times CP \\ CP=\frac{429\times100}{65} \\ CP=660 \end{gathered}[/tex]

Therefore, the price yesterday is $660.
