Jill invested $500 in an account with a compound interest rate of 6%. cheryl invests $600 in an account with a compound interest rate of 4%.find out in how many years each doubles her money. using the rule of 72, es025-1.jpg, what is the difference in the number of years to double their money?

Jill doubles her money in 12 years.

Cheryl doubles her money in 18 years.

Difference = 6 years.

Step-by-step explanation:

We have been given that Jill invested $500 in an account with a compound interest rate of 6%. Cheryl invests $600 in an account with a compound interest rate of 4%.

Since the rule of 72 states that to find the number of years it will take an amount to double, we should divide 72 by the annual interest rate.

Let us find the time it will take to double Jill's money by dividing 72 by 6 as annual interest rate is 6%.

Therefore, it will take 12 years to double Jill's money.

Now we will divide 72 by 4 to find the time it will take to double Cheryl's money.

Therefore, it will take 18 years to  double Cheryl's money.

To find the difference in the number of years to double their money we will subtract 12 from 18.

Therefore, the difference in the number of years to double their money is 6 years.

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
