Question

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

Answer 1

A. x = 200

Answer 2

b: cost of 20 books is 1270

Answer 3

C: the cost of printing w books equals p

Answer 4

D; no , because you cant print 1/2 a book

Answer 5

thank you! :) can you help with -> Using the function, determine one possible daily cost by evaluating the function for any input of your choice.

Answer 6

among the 4 choices you provide, which will give you a real evaluation of the function?

Answer 7

the textbook company can print up to 500 books in a day... which is more than 20 or 200...

Answer 8

and the last choice is not possible as @alekos said...

Answer 9

so which choice will give you the real evaluation of the function? what do you think?

Answer 10

like which of those answers? c?

Answer 11

why do you think so?

Answer 12

because you said 200 and 20 isnt enough and a is 20 and b is 200 so it must be c

Answer 13

yes it is C, because the w as the number of books is simply a variable like x that can interpret the number of books that can be print daily, it ranges from 1 to 500... and the C(w)=p, represents the corresponding daily cost...

Answer 14

w is a positive integer (number with no fractions)....

Answer 15

got the idea @emmmerrss ?
