The cost c (in dollars) per unit of making x photocopies at the office shop is given below.

--18 cents for at most 20 copies
--12 cents for more than 20 copies up to 50
--9 cents for more than 50 copies but less than 100
--5 cents for 100 copies or more but up to 200
--3 cents for more than 200 copies

(a) write the piecewise-defined function that represents the situation.
(b) explain why it would not be cost-effective to make 150 photocopies.

15: 24

62.5%

step-by-step explanation:

37 = ending with 7

unit's digit in the cube..3

56 = ending with 6

unit's digit in the cube..2

133 = ending with

unit's digit in the cube..7

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.

i think the answer is b x = 1, y = 35/2
