P(x) = 4x + 1550 <== ur function
selling only 50 copies...
P(50) = 4(50) + 1550
P(50) = 200 + 1550
P(50) = 1750....so the printing cost for 50 copies is 1750
1750 = 50x....x = cost of each book
1750/50 = x
35 = x.......u would have to sell each book for $ 35 <===
I think the coordinates are 1, 10 but not positive because if you graph it you can see a kite in it so make the point close to 4,10

QUESTION</h2>
What is 33% of 400?
<h2>
ANSWER AND EXPLANATION</h2>
To find the percent of a number, you have to change the percent into a decimal or a fraction and multiply by the number.
<h3>
DECIMAL</h3>
To change a percent into a decimal, remove the percent sign and move the decimal point 2 places to the left.

Now that you have your decimal, multiply by 400:

ANSWER = 132
<h3>
FRACTION</h3>
To change a percent into a fraction, make the percent number as the numerator(top number) and 100 as the denominator(bottom number) since fractions are out of 100.

Now that you have your fraction, multiply by 400:

ANSWER = 132
