Alexxx [7]

Answer:

Given:

Sebastian :

Principal(invested)= $7,100

Rate of interest= 8.14% compounded monthly

Eva:

Principal(invested)= $7,100

Rate of interest= 8.12% compounded continuously

Step-by-step explanation:

After 5 years,

In Sebastian case:

Amount= Principal* $(1+R/100)^{t}$

Amount = 7100* $(1+8.14/100)^{12*5}$

Amount= 7100* $1.0814^{60}$

Amount=7100*109.4415

Amount= $777,034.43

In Eva case,

Amount= Principal* $e^{Rt/100}$

Amount = 7100* $e^{0.0812*12*5\\}$

Amount= 7100*130.5818

Amount= $927,130.92

Difference between their money=$927,130.92-777034.43

=$150,096.49

Eva has $150,096 more money than Sebastian.
