<span>{2y = x + 10
{3y = 3x + 15 |:3

</span>{2y = x + 10
{y = x + 5

{2(x+5) = x + 10
{y = x + 5

{2x+10 = x + 10
{y = x + 5

{2x - x = 10 - 10

A bicycle was originally sold for $400 was on sale for $320. what percent was the bike marked down?

Eva8 [605]

100% of the price = $400
x % of the price = $320
we need to find x

using a proportion
100 : 400 = x : 320
100 * 320 = 400 * x
32000 = 400x
x = 32000 / 400
x = 80

That means the new price is 80% of the previous price.
100% - 80% = 20%
and based on this we can make a conclusion that the discount was 20%

I hope it is clear to you, feel free to ask anything about it :)
