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.
A 2 column table with Type of Editing and Cost per page as the column headings. Express Proofreading costs 3 dollars, Basic Proofreading 3.95 dollars, Extended Proofreading 5 dollars, and Deep Editing 13.00 dollars

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?

Answer 1

Gonna do a little subbing here...

for 40 pgs of express proof reading....3 bucks per pg...c = 3
40(3) - 0.05(40(3)) = T
120 - 0.05(120) = T.....120 - 6 = T.....114 = T
so  express proofreading cost 114

for 40 pgs of basic proof reading....c = 3.95
40(3.95) - 0.05(40(3.95) = T
158 - 0.05(158) = T....158 - 7.9 = T.....150.10
so basic proof reading costs 150.10

for 40 pgs of extended proof reading....c = 5
40(5) - 0.05(40(5) = T
200 - 0.05(200) = T....200 - 10 = 190
so extended proof reading is 190

no need to go further....the extended proof reading is gonna be ur answer...the best quality of editing that keeps it at 190
