Question 251845: A motor car manufacturer makes M cars per week. The production is increased
by N % The number of cars made per week is now what number?

You can put this solution on YOUR website!
n = n% / 100%.

production will be (1+n)*m cars per week.

example:

let m = 100

let n% = 20%

n = 20%/100% = .2

1+n = 1+.2 = 1.2

production will be (1+n)*m = 1.2*100 = 120 cars per week.

production has been increased by 20%.

(120-100)/100 = 20/100 = .2 * 100% = 20%
