Ayearbook printer charges based on the number of pages printed. here is a table that shows the cost of some recent yearbooks.

number of pages 50 100 150 200
cost 1.75 2.55 3.35 4.15

which equation gives the cost, y, in terms of the number of pages, x?

y = 0.016x + 0.95

y = 0.016x + 1.75

y = 0.016x + 48.25

y = 52.6x + 0.95

The cost per page can be calculated with


Since the cost is $0.80/50 pages, we subtract $0.80 to get the initial value:


So the equation is

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
