Question

Carol Wynne bought a silver tray that originally cost $135 and was advertised at 35% off. What was the sale price of the tray?The sale price was $(Type an integer or a decimal.)

Answer 1

Let:

Op = Original price

r = Percentage discount = 35% = 0.35

Sp = Sale price

We can find the sale price as follows:

`\begin{gathered} Sp=Op-r\cdot Op \\ so: \\ Sp=135-0.35\cdot135 \\ Sp=135-47.25 \\ Sp=87.75 \end{gathered}`

Answer:

$87.75
