Answer:
$1,110
Step-by-step explanation:
You have to use the interest formula to calculate how much each brother will have after a year.
A = P(1+r)^t
A = future/ending value
P = principle
R = interest rate
T = time (given in years)
Charles = 30,000(1+.025)^1 = 30,750
Brian = 30,000(1+.062)^1 =31,860
31,860-30,750=1,110
Brian will have $1,110 more than Charles after 1 year
Answer= 4 hours.
The first pipe can fill one pool in nine hours. So in one hour, it can fill 1/9th of the pool. Same with the other pipe, it can fill 1/6th of the pool in other hour.
So 1/9 + 1/6 would represent the first hour of filling the pool. Since 1/9 + 1/6 = .277.. , 27% of the pool is filled. Repeat this until you get to 100% (full pool).
First hour, 1/6 + 1/9 = .27
Second hour, 2/6 + 2/9 = .5
Third hour, 3/6 + 3/9 = .83
Fourth hour, 4/6 + 4/9 = 1.11
So in 4 hours, the pool will be filled.
