Question

Tamara purchased a CD player at a “25% off” sale for $68.25. To determine the original price, p, of the CD player, solve the equation p-0.25p= 68.25.

Answer 1

Given:

The original price is given by 'p'

The equation describing the situation is given as:

`p-0.25p=68.25`

Solving for p ,

`\begin{gathered} p(1-0.25)=68.25 \\ p(0.75)=68.25 \\ p=(68.25)/(0.75) \\ p=91 \end{gathered}`

Therefore, the original price 'p' of the CD player is $ 91.
