Answer:
Mike's savings before he saved additional money = $120
Nick's savings before he saved additional money = $90
Step-by-step explanation:
The ratio of mikes savings to nicks savings was 4:3.
Let their savings be 4k and 3k.
After mike saved another $120 and nick saved another $60, their savings become 4K+120 and 3k+60.
It is given that the new ratio is 8:5.
Therefore,
4k+120 : 3k+60 = 8:5
5(4k+120) = 8(3k+60)
20k+600 = 24k+480
20k-24k = 480-600
-4k = -120
k = 30
So, Mike's savings before he saved additional money = 4k = 4(30) = $120
Nick's savings before he saved additional money = 3k = 3(30) = $90
