Nick invests $3,500 in an account earning 11% interest compounded annually. Krista invests $4,000 in an account earning 4% interest compounded annually. Who will have more money in their account after 2 years? How much more?

Answer:
Krista's have more amount by $14.05
Step-by-step explanation:
Nick's Case
Principal = $3500
Rate of interest = 11% = 0.11
Time = 2 years
Formula : [tex]A=P(1+R)^t[/tex]
[tex]A=3500(1+0.11)^2[/tex]
[tex]A=4312.35[/tex]
Krista's case
Principal = $4000
Rate of interest = 4% = 0.04
Time = 2 years
Formula : [tex]A=P(1+R)^t[/tex]
[tex]A=4000(1+0.04)^2[/tex]
[tex]A=4326.4[/tex]
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
