To complete a task in 15 days a company needs 4 people each working for 8 hours per day. the company decides to have 5 people each working for 6 hours per day. assume that each person works are the same rate. how many days will the task take to complete?

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.
