Darnell and Stephanie have competing refreshment stand businesses. Darnell's profit can be modeled with the polynomial c? + 8C – 100,
where c is the number of items sold. Stephanie's profit can be modeled
with the polynomial 2c? – 70 - 200.
a. Write a polynomial that represents the difference between Stephanie's
profit and Darnell's profit.
b. Write a polynomial to show how much they can expect to earn if they
decided to combine their businesses.
