Question

a video ggame originally priced at $65.50 is on sale at a 15% discount. What is the sale price of the video game

Answer 1

Let:

Op = Original price

r = Discount percent

Dp = Discount price

1st, express the percentage as a decimal:

15% = 15/100 = 0.15

so:

`\begin{gathered} Dp=Op-r\cdot Op \\ Dp=65.5-0.15\cdot65.5 \\ Dp=65.5-9.825 \\ Dp=55.675 \end{gathered}`

Answer:

$55.675
