Answer:

Step-by-step explanation:

Ok, so we know that there are 30 marbles

to find the amount of blue marbles we need to find 10percent of 30

10percent of 30= 30/10=3

3blue mables

60percent of 30=18

18red marbles

18+3=21

30-21=9 yellow marbles

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 :)
