Answer:
23.3 years
Step-by-step explanation:
4000 = 2136.7(1 + .027/4)^(4t)
4000 / 2136.7 = 1.00675^4t
ln (4000 / 2136.7) / ln 1.00675^4 = t
23.301690290541729158877031400229 = t

1:3:4
1x:3x:4x
1x + 3x + 4x = 8x
8x = 56
x = 7
1(7) = 7
3(7) = 21
4(7) = 28
Check: 7 + 21 + 28 = 56
So 56 can be divided in the ratio of 1:3:4, and it will be 7, 21, 28
