Answer:
The utilization rate with the minimum number of voters = 0.75
Step-by-step explanation:
Rate of arrival of voters = 27 voters per hour
If each voter spends 5 minutes in the voting booth,
In 1 hour, number of voters = 60/5 = 12. i.e. service rate = 12 voters per hour
Utilization rate, UR= 
...............(1)
Maximum value for UR = 1. i.e UR ≤ 1
number of voters cannot take a decimal value, therefore,
The minimum number of voters = 3
Substituting number of voters into equation (1)
I would go with the answer D
If you would like to solve the system of equations, you can calculate this using the following steps:
6x – 3y = 3
–2x + 6y = 14 /*3
_________
6x – 3y = 3
<span>–6x + 18y = 42
</span>_________
-3y + 18y = 3 + 42
15y = 45
y = 45/15
y = 3
<span>6x – 3y = 3
</span>6x - 3 * 3 = 3
6x = 3 + 9
6x = 12
x = 12/6
x = 2
(x, y) = (2, 3)
The correct result would be (2, 3).
X=.8(50)
x=40
Therefore 40 is 80% of 50.
Hope this helps!
(Also the formula I used is: part = percent * whole)
