Question

A yearbook 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 : 1.55, 2.25, 2.95, 3.65


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



A.


y = 0.014x + 49.15


B.


y = 0.014x + 1.55


C.


y = 0.014x + 0.85


D.


y = 58.8x + 0.85

Answer 1

(3.65 -2.95 )/ (200-150) =m

Answer 2

soooooo like y-3.65= 0.014 (x-200) and you distribute 0.013x-2.8=y-3.65

Answer 3

add 3.65 on both sides

Answer 4

y=0.014x +0.85

Answer 5

Thank you!

Answer 6

no problem
