sorry it won't let me show step by step but your answer is 150x-17
With the equation:
0.15 x = 30
x = 30 : 0.15 = $200
A regular price of TV is $200.
Which could not be used to determine x ( we shall plug in the value 200 ):
A ) 0.15 * 200 = 200 - 30
30 ≠ 170
B ) 0.85 * 200 = 200 - 30
170 = 170 ( correct )
C ) 200 - 0.15 * 200 = 200 - 30
200 - 30 = 200 - 30
170 = 170 ( correct )
D ) 0.15 * 200 = 30
30 = 30 ( correct )
Answer:
A ) 0.15 x = x - 30
Answer: You need more information to solve this, is there another part of the question?
Step-by-step explanation:
If order doesn't matter (e.g. all the positions in the committee are essentially identical) then the number of possible choices is
.
8 1/2 = 8 4/8, so…
8 4/8-2 5/8= 6 1/8
Final answer is…
6 1/8
