Answer:

$546.25 is the total pay for that week

Step-by-step explanation:

Allen makes $11.50 per hour. That means that if he works 40 hours per week, he will make 460$.

$11.50 * 40 hours = $460 per week

Overtime is any number of hours he works over 40 hours per week. Allen makes 50% more for every hour of overtime. Instead of making 11.50, he will be making $17.25.

$11.50 * 1.5 = $17.25 per hour of overtime

--------------------------------------------------------------------------------------------------------------

To solve the problem:

1. How many hours were worked total on that particular week?

2. How many hours were normal time, how many were overtime?

3. Multiply normal time hours by $11.50, overtime hours by $17.25.

4. Add them together for the total compensation

Solution:

The week of 5/17, Allen worked 45 hours total. This is 40 hours of normal time, 5 hours of overtime.

40 hours * $11.50 = $460.00

5 OT hours * $17.25 = $86.25

$460.00 + $86.25 = $546.25 is the total amount earned that week.

For a given data group, simple exponential smoothing is being used to forecast demand. The forecast of a given period is 110, wh

Answer:

The smoothing constant alpha is 0.20 (Option a)

Step-by-step explanation:

To solve this problem, first we write the succession of the simple exponential smoothing:

$s_t=\alpha x_t+(1-\alpha)s_{t-1}$

Where s(t) is the forecast for period t, s(t-1) is the forecast for period (t-1), xt is the real demand for period t, and alpha is the smoothing constant.

All but the alpha constant are known

s(t)=109.2

s(t-2)=110

xt=110-4=106

Then, we can calculate alpha as:

$s_t=\alpha x_t+(1-\alpha)s_{t-1}\\\\109.2=\alpha*106+(1-\alpha)*110\\\\109.2=(106-110)\alpha+110\\\\(110-106)\alpha=110-109.2=0.8\\\\4\alpha=0.8\\\\\alpha=0.2$
