Answer:

$546.25 is the total pay for that week

Step-by-step explanation:

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

<em>$11.50 * 40 hours = $460 per week</em>

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

<em>$11.50 * 1.5 = $17.25 per hour of overtime</em>

<em>--------------------------------------------------------------------------------------------------------------</em>

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.

8x(14+7)=14+(8x7) what is the value I use
Serhud [2]

The equation seems to be invalid. Is that the equation from your homework? Both sides of the equation dont seem to be equal to each other. This equation would have no solution, instead of one or infinite solutions.
