Answer
A
Step-by-step explanation:
First, lets go through B-D and explain why they are correct.
B= f represents the number of flash drives. This means that the coefficient, 10, would be the cost per flash drive.
C= n represents the number of cases of paper. it says so in the question, so that one is a bit easier.
D= f represents the amount of packages of hanging folders. If the coefficient for B is the cost, then that would be the same case for D. Therefore it is correct because the coefficient is 13.
A would be incorrect because the coefficient represents the amount that one item costs. P is the packs of pencils, meaning that it would be $7 per pack of pencils.
Hope this helps!
Question:
Solution:
Note that if we evaluate x = -1, 0, and x=1 in the last equation we get:
y = 3(-1)+ 3 = -3+3 = 0
y = 3(0)+3 = 3
y = 3(1)+3 = 6
So that, we can conclude that the correct solution is
D. y =3x + 3
