Answer:
$5,172.93
Step-by-step explanation:
We're gonna use the simple interest formula: P = A(1 + r(t))
P = final amount
A = starting amount (4,678)
r = rate (0.073)
t = years (529/365)
P = 4,678(1 + 0.073(529/365))
P = 5,172.9324

Answer:
17
Step-by-step explanation:
Let us suppose two years ago my brother's age was x years
Then, my age was 3x
Three years from now, my brother's age will be (x +2+3) = (x+5) years
And my age will be (3x+2+3) = (3x+5) years
But it is given that i will be twice as old as my brother.
So, 2(x+5)= (3x+5)
or, x= 5 years
So my brother's present age is 5+2= 7 years
And my age is 5*3+2= 17 years
