Question

Items are 50% off. Cora buys a red bandana during the sale. If Cora pays $2, what was the original price?

Answer 1

the bandanna was originally $4

Explanation:

`%50` is the same as `1/2` so if you solve `x=n+x*m` where m is the fraction equivalent of the percentage and n is the price after the discount, `x=2+x/2` so if you take `x/2` from each side you get `x/2=2` which means `x=4`

Answer 2

`$4`

Explanation:

YOu can use direct proportion.

`100%-50% = 50%`

The price of `$2` represents `50%`, how much is the `100%?`

`2/50 = x/100`

`x = (100xx2)/50`

`x =$4`

YOu could also have seen the the values on the right are double the values on the left.

`2/50 xx 2/2 = x/100`

`x = 2xx2=4`
