Explain why the total revenue from the sale of x shirts at the price p(x) is R(x)=16x-0.005x^2 where Rx=dollar

You have identified the following costs:
Heat Press: 612.50
Shirts in Bulk: 2.50
Transfers to press on shirts: 1.00

Write a function C(x), that gives the total cost of producing shirts: ?

Target Shirt sales, x | Price Per shirt P
500 = 13.5$
900 = 11.5$
1300 = 9.5$
1700=7.5$
2100= 5.5$
2500= 3.5$

Based on that info, write a function p(x) that gives the selling price per shirt that would enable you to sell x shirts during the semester. P(x)???

Explain why the total revenue from the sale of x shirts at a price p(x) dollars per shirt is given by R(x)=16x-.005x^2 where R(x) is in dollars

Since Profit = Revenue - Cost, wrie tthe function P(x), that gives the net profit from the sale of x shirts

Write an inequality for the following: How many t-shirts must you sell to make a profit?

Thank you anyone for any help/answers/advice that you may have to offer. I think I may have some of these answers but I doubt that they're right. Any help is appreciated.

Need help with this question about speed. PLEASE?

In Denver, children bring their old jack-o-lanterns to the top of a tower and compete for accuracy in hitting a target on the ground. Suppose that the tower height is h = 10.80 m, and that the bulls-eye's horizontal distance is d = 3.9 m from the launch point. If the pumpkin is thrown horizontally, what is the launch speed needed to hit the bulls-eye? (Neglect air resistance.)

Thank you very much i have been stuck on this problem for awhile now. God Bless.

How do I put this word problem into an equation?

I believe it's a non-linear equation, but am once again stumped. A student charges $7 to wash a window. He washes 15 of them for $35. Write an equation.

Well, I've figured that the 1st window is $7 and all subsequent windows are $2 a piece. I've tried to write the equation so that when you enter a "0" for x, you would get "0," as if the student is washing "0" windows, they will get paid "0" dollars. Now, I just need to figure out how to write the equation.

The one with the most details gets the 10 points, as I am not just looking for the answer, because I want to understand what's going on.
