A grower has 100 tons of potatoes that she can sell for a profit of $500 per ton. Foreach week that she delays shipment, she can produce an additional 10 tons of potatoes. Unfortunately for each week she delays the profit decreases $25 a ton. Write a quadratic function to represent the profit and use it to determine when she should ship to maximize her profit and find the value of this maximum profit.

Solve the following: 12(x^2–x–1)+13(x^2–x–1)=25(x^2–x–1) 364x–64x=300x

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.
