The ratio of the number of apples Nicole and Hannah had was 1:3. When Nicole bought 4 more apple and Hannah bought 3 more apples, the ratios became 1:2. Find the number of applles Hannah had in the end.

Originally    n = 3 h

 

then     n+4  =  2 ( h+3 )       sub in the first equation

           3h + 4 = 2 ( h +3)

           h = 2              2 + 3 = 5 apples in the end for H

originally, I think since n/h=1/3, h=3n, not n=3h

n-number of apples Nicole has at first

h-number of apples Hannah has at first

 

n/h=1/3

h=3n

(n+4)/(h+3)=1/2

2n+8=h+3

substitute h=3n

2n+8=3n+3

n=5

h=15

15+3=18
