Answer: 0.5747

Step-by-step explanation:

Given: Average time to serve a customer(\mu)=4.35 minutes

standard deviation of the service time (\sigma)= 2.5 minutes

coefficient of variation = \frac{\sigma}{\mu}

=\dfrac{2.5}{4.35}\\\\=\dfrac{250}{435}\\\\=0.5747

Hence, the required coefficient of variation= 0.5747

Answer:

2x + 9y = 60

10x + 5y = 60

The price of each bag of popcorn is $6.

Step-by-step explanation:

Let each drink costs $x and the price of each bag of popcorn is $y.

So, from the given two conditions we can write two different equations as

2x + 9y = 60 ............... (1) and

10x + 5y = 60 ................. (2)

Now, solving those two equations we get,

5(60 - 9y) + 5y = 60

⇒ 300 - 45y + 5y = 60

⇒ 40y = 240

⇒ y = 6

Therefore, the price of each bag of popcorn is $6. (Answer)
