Answer:
Connor earns more interest than Wendy.
Wendy earns an interest of 7262.50 while Connor earns an interest of 11312.90
Step-by-step explanation:
The initial amount that Wendy and Connor deposited is 8300.
They both earn interests of 3.5%.
We will calculate the interest of each of them.
WENDY (Simple Interest)
Simple Interest is given as:
[tex]I = \frac{P*R*T}{100}[/tex]
where P = principal = 8300
R = rate = 3.5%
T = number of years = 25 years
Therefore, her interest will be:
[tex]I = \frac{8300 * 3.5 * 25}{100} = 7262.50[/tex]
CONNOR (Compound Interest)
Compound interest is given as:
[tex]I = P(1 + R)^T -P[/tex]
Therefore, his interest will be:
[tex]I = 8300(1 + \frac{3.5}{100})^{25} - 8300\\ \\I = 8300( 1 + 0.035)^{25} - 8300\\\\I = 8300(1.035)^{25} - 8300\\\\I = (8300*2.363) - 8300\\\\I = 19612.9 - 8300\\\\I = 11312.90[/tex]
Therefore, Connor earns more interest than Wendy. Wendy earns an interest of 7262.50 while Connor earns an interest of 11312.90.
Note: The amount in the question is unitless, that is why my answers are also unitless.
