Thanks in advance.
An airline sells all the tickets for a certain route at the same price. If it charges 200 dollars per ticket it sells 10,000 tickets. For every 45 dollars the ticket price is reduced, an extra thousand tickets are sold. Thus if the tickets are sold for 155 dollars each then 11,000 tickets sell. It costs the airline 100 dollars to fly a person.
(a) Express the total profit P in terms of the number n of tickets sold.
(b) Express the total profit P in terms of the price p of one ticket.
(a) P(n)= _____ $
(b) P(p)= _____ $

Question 740841: I am trying to create a three circle Venn diagram with unions and intersections. I can answer the question written out in a list form, but I can't seem to understand how it looks on a three circle Venn diagram. We are using attribute blocks via a virtual manipulative kit. There are 3 colors - red, blue, yellow; 4 shapes - square, circle, hexagon and triangle and 2 sizes - large and small. So total, there are 24 different attribute blocks. The question we were given is to show: (S U T) U NR, which is (square union triangle), union not red. I understand union will include all of those things, but again, can't seem to understand what that will look like on a Venn diagram.
Since I can't upload the picture I took, it looks like this: top left circle - all squares, top right circle - all triangles, bottom circle - anything that isn't red, outside the circles - red circles and red hexagons. HELP!!!
