Respuesta :

3) is y=x because they are directly proportional.

4) is $20 per uniform (read one unit of the graph)


5) is $160 for 8 uniforms
For number 3, the answer will be A because we have the formula to find this which is y/x or 20/1 or 40/2, or 60/3. For number 4, we know that it will cost 20 dollars to buy one uniform base on the graph that show above which is D. For number 5, it will take 160 dollars to buy 8 shirts if one shirt cost 20 dollars which is C. Hope it help!
