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