Question

Sean, 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. Sean also gives a 5% discount if the entire amount is paid up front.
Michelle has an 85-page manuscript. The equation below shows the relationship between the total cost of editing 85 pages, T, and the cost per page, c, if she gets the 5% discount:

85c − 0.05(85c) = T

Using the equation, what is the best quality of editing that Michelle can get done for a maximum of $161.50?
Express proofreading
Basic proofreading
Extended proofreading
Deep editing





Choose the correct description of the graph of the compound inequality:

x − 3 < −7 or x + 5 ≥ 8
A number line with an open circle on −4, shading to the left, and a closed circle on 3, shading to the right
A number line with a closed circle on −4, shading to the left, and an open circle on 3, shading to the right
A number line with an open circle on −4, a closed circle on 3, and shading in between
A number line with a closed circle on −4, an open circle on 3, and shading in between

Answer 1

85c - 0.5(85c) = 161.5
85c - 4.25c = 161.5
80.75c = 161.5
c = 161.5 / 80.75
c = 2............so she needs express proofreading
==================
x - 3 < -7                  x + 5 > = 8
x < -7 + 3                 x > = 8 - 5
x < -4                       x > = 3

open circle on -4, shading to the left....closed circle on 3, shading to the right
