Erika can twice the decimal value of 1/3 to find the decimal value of 2/3. The decimal value of 2/3 is about 0.67.

Step-by-step explanation:

Let Erika wrote the decimal value for 1/3 . She needs to use this decimal value to find the decimal value of 2/3.

Write the fraction value 2/3 in the factor 2 and 1/3.

Substitute the decimal value of 1/3 in the above equation.

Erika can twice the decimal value of 1/3 to find the decimal value of 2/3. The decimal value of 2/3 is about 0.67.

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
