Explanation:
Nick's Case
Principal = $3500
Rate of interest = 11% = 0.11
Time = 2 years
Formula :
![A=P(1+R)^t](https://img.qammunity.org/2019/formulas/mathematics/high-school/s4dqflo1ugsug6h710sv6fnj4l5pgrkhxv.png)
![A=3500(1+0.11)^2](https://img.qammunity.org/2019/formulas/mathematics/high-school/nqqa32sl4ma2xjrdvs5g2g701rk23t6f0b.png)

Krista's case
Principal = $4000
Rate of interest = 4% = 0.04
Time = 2 years
Formula :
![A=P(1+R)^t](https://img.qammunity.org/2019/formulas/mathematics/high-school/s4dqflo1ugsug6h710sv6fnj4l5pgrkhxv.png)
![A=4000(1+0.04)^2](https://img.qammunity.org/2019/formulas/mathematics/high-school/2vimsjgfngeb7rosia7s4474hqclquwys3.png)
![A=4326.4](https://img.qammunity.org/2019/formulas/mathematics/high-school/eoqngwdiyruvb5jl0up0e49qkal3iqvbvs.png)
Nick's amount = $4312.35
Krista's amount = $4326.4
So, Krista's have more amount
Difference = $4326.4-$4312.35=$14.05
Hence Krista's have more amount by $14.05
