Darnell and Stephanie have competing refreshment stand businesses Darnell's profit can be modeled with the polynomial c^2 + 3c - 120, where c is the number of items sold. Stephanie's profit can be modeled with the polynomial 3c^2+ - 7c- 400. Write a polynomial that represents the difference between Stephanie's profit and Damell's profit.

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.
