It really just depends on how fast or how slow they eat but the second brother will get done eating first
A(t) = P(1+(r/n))^(nt)
A(3) = 500(1+0.04/1))^(1*3)
A(3) = 500(1.04)^3
A(3) = $562.43
The correct answer to this question is 0.064.
Here's how to simplify the expression (0.4)^3.
We have to multiply 0.4 three times.
(0.4)^3 = <span>0.4 * 0.4 * 0.4
(0.4)^3 = 0.16 * 0.4
(0.4)^3 = 0.064
The simplified answer is 0.064</span>
