C. If Jackie's money is compounded continuously, how long will it take her money to double?
d. If Jackie's money is compounded monthly, how long will it take her money to triple?

a. $1251.5

b. $1254.64

c. 15.4 years

d. 30.56 years

Step-by-step explanation:

Given the information:

As we know, the formula to find the future value of Jackie deposit with interest is compounded monthly, quaterly, ..is

 where:

Hence:

a. If the interest is compounded quarterly how much money will Jackie have in 10 years?

<=>  

<=> A = $1251.5

d. If Jackie's money is compounded monthly, how long will it take her money to triple?

<=>

<=>

<=>

<=> t = 30.56 years

As we know, the formula to find the future value of Jackie deposit with interest is compounded continuously

A = P* where e is the mathematical constant approximated as 2.7183.

b. If the interest is compounded continuously how much money will Jackie have in 10 years?

<=> A = 800*

<=> A = $1254.64

C. If Jackie's money is compounded continuously, how long will it take her money to double?

<=> P*  = 2*800

<=> 800* = 1600

<=> = 2

<=> t = 15.4 years
