Question

A yearbook printer charges based on the number of pages printed. Here is a table that shows the cost of some recent yearbooks. Paper 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?
(Points : 1)
y = 0.014x + 49.15
y = 0.014x + 1.55
y = 0.014x + 0.85
y = 58.8x + 0.85
