Question

Please help me with a question!!! :)

Answer 1

Find the equation of the line in the graph and mathematically model the scenario using function notation where cost is a function of number of minutes.
cell phone plan graph : Line starting at (0, 20) and going through 400, 40
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.
For what value of x does C(x) = 1900?
Interpret the statement C(20) = 1270.
Interpret the statement C(w) = p.
Explain whether C(40.5) = 1341.75 is correct and possible given the context of this problem.

Answer 2

i need help with the last two questions

Answer 3

So can you help??

Answer 4

the C(w)=p is saying that for every whole textbook you buy it equals to the p which is the price

Answer 5

so the cost would be 5.9

Answer 6

now the last sentence is not correct since you are buying whole book they can not give you just 10 pages out of the 100 pages of a book

Answer 7

oh okay i understand now

Answer 8

thnx for explaining :)

Answer 9

np :D
