Ms. Cathy bought a package of pencils. Out of every 10 pencils, 5 are black. If there are 50 pencils in the pack, what fraction of the pencils in the pack are black? What percent of the pencils in the pack are black?

What fraction of the pencils in the pack is black?

What percent of the pencils in the pack are black?

2/4 and 50%

Step-by-step explanation:

Answer 50%

Step-by-step explanation:

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.
