Question 935163
let A represent the amount of money that A has.
let B represent the amount of money that B has.
let C represent the amount of money that C has.


A = B + .20 * B = 1.20 * B


C = B - .20 * B = .8 * B


A / C = (1.20 * B) divided by (.8 * B) which is equal to 1.20 / .8 which is equal to 1.5


A has 1.5 * the amount of money that C has.


1.5 * C - C is equal to .5 * C.


A has 50% more money than C has.


let's see how this works out.


Assume that B has 100 dollars.


then:


A has 120 dollars.
C has 80 dollars.


A - C = 120 - 80 = 40


this means that A has 40 dollars more than C.


40 / 80 = .5 = 50%


this means that A has 50% more dollars than C has.
