So first off you need common denominators. So what is eaiser for me, I just multiply 5*7. Which equals 35. Now you need to do that to the top. So you take 7*3 and 5*3. So then you would have 21/35+15/35. So then the answer is 36/35 simplified. 1 1/35

A person places $37700 in an investment account earning an annual rate of 5%,

lorasvet [3.4K]

Answer:

8,229,437 cents

Step-by-step explanation:

Using the compound interest formula;

A = P(1+r)^n

Given

Principal invested = $37700

rate r = 5% = 0.05

Time t = 16years

Substitute into the formula

A = 37700(1+0.05)^16

A = 37700(1.05)^16

A = 37700(2.1829)

A = 82,294.37

Hence the amount of money, to the nearest cent, in the account after 16 years is 8,229,437 cents
