Question

Jay, a freelance editor, charges the rates shown in the table below to edit manuscripts. The cost per page increases as the quality of editing improves. Jay also gives a 5% discount if the entire amount is paid up front.

'Type of Editing' and 'Cost per page' as the column headings.

Express Proofreading costs $3.00,
Basic Proofreading - $3.95
Extended Proofreading - $5.00
Deep Editing - $13.00
Ellen has a 40-page manuscript. The equation below shows the relationship between the total cost of editing 40 pages, T, and the cost per page, c, if she gets the 5% discount.

40c - 0.05(40c) = T

Using the equation, what is the best quality of editing that Ellen can get done for a maximum of $190?

A) Express proofreading
B) Basic proofreading
C) Extended Proofreading
D) Deep editing

Answer 1

plug the cost of each quality into the equation. Whichever will get you the highest number for T but still be less than 190 is the most she can afford.

Answer 2

if you just want the answer, or to check against your answer, it is the extended proofreading.

Answer 3

because 40(5)-.05(40(5))=190, which is the highest she can spend without going over 190
