4) d. 30%. 5) 55/21. 6) 16

Step-by-step explanation:

4) 6/20 × 100 = 30%

5) Change mixed numbers to fraction. So you're getting 58/7 - 17/3. LCM = 21

= 174 - 119 / 21

= 55 / 21

6) Change to fraction

8/3 ÷ 1/6

= 8/3 × 6/1

= 16

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.
