Maria has a 25-page manuscript. The equation below shows the relationship between the total cost of editing 25 pages, T, and the cost per page, c, if she gets the 5% discount. 25c - 0.05(25c) = T Using the equation, what is the best quality of editing that Maria can get done for a maximum of $66.50?

what a weird formula first off \[25c - 0.05(25c)=25c(1-.05)=25c\times .95\]

OpenStudy (anonymous):

to decrease by 5% you multiply by \(.95\) so the equation really reads \[23.75c=T\] you want \(T=66.5\) set \[23.75c=66.5\] solve for \(c\) via \(c=66.5\div 23.75\)

as for the rest, there is some information missing, but i am sure you can get it from there

In other words, c = 2.8 Basic proofreading.
