How do you solve this math problem? What is the equation?

Question

Prissy’s Copy Center charges $2.45 for binding plus 4¢ per page to copy a manuscript. Estimate the length of the manuscript if Maria paid approximately $15.50 for the copying.

Answer 1

Let n be the number of pages:

The cost is 4 cents per page (0.04n) plus a single binding charge of 2.45. This totals 15.50, so the equation is:

0.04n + 2.45 = 15.50

Subtracting 2.45 from both sides:
0.04n = 13.05

Dividing both sides by 0.04:
n = 13.05 / 0.04

It might be easier to multiply the numerator and denominator by 100:
n = 1305 / 4
n = 326 1/4

I'm not sure how she managed to get that 1/4 page counted...

Anyway, approximately 326 pages

Answer 2

ok, the excellent thank you to do it quite is using algebra. it quite is the place you write a letter in place of an excellent determination you do no longer understand. enable me instruct you. a million) enable's call the two numbers A and B all of us understand "the sum of two huge type is 30" so A + B = 30 "the 2d huge type is two better than three times the 1st" so B = 2 + 3*A we now have 2 equations and all we ought to do is sparkling up them! There are quite some information on the thank you to try this, yet what i could do is that this. A + B = 30 yet B = 2 + 3*A So A + (2+3*A) = 30 A + 2 + 3*A = 30 4A = 28 A = 7 yet on condition that A + B = 30, B = 23 = ) 2) the 2d would be very comparable. A + B = 22 thus and four*A = 3 + B is the different one. you may rearrange the 2d so it sounds like 4A - 3 = B if it makes it much less complicated. i'm going to pass away you to it there, given which you may sparkling up it interior the comparable way I confirmed you for the 1st one. superb of success :-) persist with it.

Answer 3

Here is the Equation:
(15.50 - 2.45) / .04

Here is the explanation.
They charge a set fee, for binding equal to $2.45. This fee does not change based off of the number of pages.
So you subtract this from the total.
Then you divide the remaining amount by the price per page.

The Answer is:
$326.25

Answer 4

If she paid $15.50 for the copying and it cost 4 cents per page, then it's 1550 / 4. The binding charge is irrelevant, because the question states $15.50 was for the copying and mentions nothing about the binding.

But assuming what your teacher meant was $15.50 was for both binding and copying, then the formula is:

(1550 - 245) / 4

and you get the number of pages with the cost of binding.

Answer 5

326 Subtract 2.45 from 15.50 and you get 13.05. You get 25 pages per dollar, 25 X 13 = 325 plus 1 = 326 and 1 cent spare.

Answer 6

subtract 2.45 for binding cost from 15.50 then divide the leftover amount by .04 to find how many pages Maria has. I think it more than 6 pages. I have to get to class, but I hope this helps.

Answer 7

$15.50 is the sum of the binding and copying. $2.45 is the binding, so the rest is copying. $2.49 for one page, $2.53 for two pages, $2.57 . . . you see the idea.

First equation: C = 2.45 + P * 0.04 (C is dollars, P is pages)

Put C in cents and shuffle it around: 245 + 4P = C, 4P = C - 245, P = (C - 245) / 4, substitute C = 1550, get P = (1550 - 245) / 4 = 1305 / 4 = 326 pages.

Answer 8

this is the equation:
2.45 + .04x = 15.50
where x is the number of pages


to solve:

subtract 2. 45 from each side...
.04x = 13.05

then divide each side by .04...
x = 326.25

since $15.50 is only an approximate value, you can just assume there were 326 pages.

Answer 9

Let x be the number of page copied.

1. Assumed that she did order biding:

Total charge: $15.50 = $2.45 + $0.04*x

=> x = ($15.50-$2.45)/$0.04 =326.25

Approximate 327 pages.

2. Assume that she did not order binding:
Total charge: $15.50 = $0.04*x

=> x = ($15.50)/$0.04 =387.5

approximate 388 pages!

Answer 10

15.50 - 2.45 = 13.05
13.05 / .04 =326.25

About 326 Pages
