R=rita's age
m=mother's age
g=grandmother's age
mother is 4 times as old as rita
m=4r
grandmother is 2 times as old as mother
g=2m
sum is 104
r+m+g=104
subsitute 4r for m and 2m for g
r+4r+2m=104
subsitute 4r for m
r+4r+2(4r)=104
r+4r+8r=104
13r=104
divide both sides by 13
r=8
4r=m=32
8r=2m=g=64
rita is 8
mother is 32
grandmother is 64
First, let's make an equation as to how to find how much money they have altogether:
(M stands for the # of month)
Jaclyn: 120 + 40m
Pedro: 180 + 20m
So let's plug-in 1 for m (1 will stand for 1 month)
Jaclyn: 120 + 40 * 1 = 160
Pedro: 180 + 20 * 1 = 200
I made a table depicting how much they'll make for the next 5 months (attached below). According to that, on month 3, they will have made the same amount of money (or $240).
So they will have the same amount of money in 3 months. Hope this helps! :)
