It would be 20% because if you take 100 times 1/5, which is the same as 100/5, you would get 20, which is 1/5.
$ per min is a rate. you multiple by minutes to get dollars.
A = 10x
B = 5x + 20
set them equal to find minutes, x.
10x = 5x + 20
10x - 5x = 20
5x = 20
x = 4
You simply divide 678 by 3 and get 226.
