color : 40p + 50f + 90
b&w : 15p+20f + 45
p = 26
f = 45
[substitute the values given]
color : 40(26) + 50(45) + 90
b&w : 15(26)+20(45) + 45
[solve the equation]
color : 3380
b&w : 1335
[subtract to see how much ink is saved]
3380 - 1335 = <u>2045</u>
Before beginning to solve these kinds of questions, always check if it's really necessary to distribute them.
You can divide both sides by -3 in order to get:
x + 5 = 3
Subtract both sides by 5:
x = -2
-T.B.

Answer:
C. 2.6666666666666
Step-by-step explanation:
You can estimate.
We know that 3 * 2 = 6.
So, we know that The decimal is at least 2.
We can cancel out B and D.
2.6 * 3 = 7.18
So, we can cancel out A.
Just to make sure, let's try C.
2.6666666666666 * 3 = 7.999999...
This is the closest answer to 8.
So, our answer is C.
C. 2.6666666666666
