Help??? 3.A textbook company keeps track of its daily cost for printing whole textbooks to different schools, but can only print up to 500 books a day. The daily cost (C) to print x number of textbooks is given by C(x) = 3.50x + 1200.

A.Using the function, determine one possible daily cost by evaluating the function for any input of your choice.
B.For what value of x does C(x) = 1900?
C.Interpret the statement C(20) = 1270.
D.Interpret the statement C(w) = p.
E.Explain whether C(40.5) = 1341.75 is correct and possible given the context of this problem.

please, for option A, you can evaluate the maximum daily cost, namely:
C(500)=3.5*500+1200=...
please complete

for option B. you have to solve this equation, please:
$$3.5x+1200=1900$$

michele_laino · Answer

of course, you have to find the value of x
