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 1.25 1.85 2.45 3.05

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

y = 0.012x + 0.65

y = 0.012x + 1.25

y = 0.012x + 49.985

y = 83.3x + 0.65

Using the first X and Y value replace the values in the equation and see which one works:

1.25 = 0.012(50) + 0.65

0.012(5) = 0.6 +0.65 = 1.25

The first equation works

Now try the second set: of values to check:

1.85 = 0.012(100) +0.65

0.012*100 = 1.20 + 0.65 = 1.85

The first equation is the correct one.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
