6) There are 272 people in an audience. The ratio of adults to children is 5 . 10 points : 3. How many are children? *

There should be 170 adults and 102 children

Step-by-step explanation:

Number of adults: 5/(5+3) times 272

Number of children: 3/(5+3) times 272

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.
