To earn money, George types papers for college students. For regular term papers, he charges by the page: $1.50 each. For scientific and technical papers, he charges more because they take longer to type. If he types forty-five regular pages and thirty-six technical pages, how much will he earn?

What other information is needed to solve this problem?

what kind of computer he is using
how long it takes him to type a page of technical writing
how much he charges for a page of technical typing
how wide his margins are

just answer this one nevermind the rest

Answer 2

you give the rate for regular papers: 1.50 per page
But you need to give the rate for scientific papers.
So, if he charges $x for those, his total charge will be

45 * 1.50 + 36x

Answer 3

1. 27/3 = 9.
9/3 = 3.

2. P = 2L+2W = 20.
A = L*W = 24.
L = 24/W
In Eq1, replace L with 24/W and solve for W:
2(24/W)+2W = 20.
48/W+2W = 20
48+2W^2 = 20W
2W^2-20W+48 = 0
W^2-10W+24 = 0. 24 = -6*-4, sum = -10 = B.
(x-6)(x-4) = 0
W = 6, and 4. Use the larger number, 6.
L*W = 24
L*6 = 24
L = 4 in.
