What is the implied service rate per service counter employee at an airport automobile rental counter if customer demand is 36 c

mart [117]

Answer:

24 customers per hour

Step-by-step explanation:

The service rate is given by the demand of customers per hour per employee divided by the labor utilization.

If there are two service counter employees on duty, the demand of customers per hour per employee is:

$D=\frac{36}{2}=18\ customers/hour$

Assuming a 75% labor utilization, the service rate is:

$S =\frac{18}{0.75}=24\ customers/ hour$

Steven earns extra money babysitting he charges $33 for 4 hours and $57.75 for 7 hours entering an equation to represent the rel

sweet [91]

Answer:

Step-by-step explanation:

<u>Linear Modeling</u>

Some events can be modeled as linear functions. If a situation comes where a linear model is suitable, then we need two sample points to make the model and predict unknown behaviors.

The linear function can be expressed in the slope-intercept format:

$y=mx+b$

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:

$\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

Let's use linear modeling to represent Steven's earnings he makes babysitting. Call y the money he charges by x hours of work.

We know he charges y1=$33 for x1=4 hours, and y2=$57.75 for x2=7 hours. The ordered pairs are (4,33) and ( 7, 57.75)

Computing the equation of the line we have:

$\displaystyle y-33=\frac{57.75-33}{7-4}(x-4)$

Operating:

$\displaystyle y-33=\frac{24.75}{3}(x-4)$

$y - 33 = 8.25( x - 4 )$

$y = 8.25x - 33 + 33$

y = 8.25x

There is a proportional relationship.
