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.

I need some help with this worksheet! Major points !!! . (not good with percentages)
yuradex [85]

To make the equations you must first get the percents and make them into a decimal. then multiply the money by the decimal

EX: $230.76 with a profit of 30%

First make the percent a decimal to do so move the . over to the left two times resulting in the number .30

so the equation is 230.76(.30)

which equals 69.228

now simplify it making the answer $69.23

now to get the store price, add manufacture price with the %30 of the the MP resulting in the answer

$299.99

X^2 + 5x = quadratic equation <br>=​
timama [110]

Hi there!

The question gives us the quadratic equation , and it tells us to solve it using the quadratic formula, which goes as . However, we must first find the values of a, b, and c. The official quadratic equation goes as , which matches the format of the given quadratic equation. Hence, the value of a would be 1, the value of b would be 5, and the value of c would be 3. Now, just plug it back into the quadratic equation and simplify to get the zeros of the equation. 

x = \frac{-b \pm \sqrt{b^2 - 4ac} }{2a}  

x = \frac{-(5) \pm \sqrt{(5)^2 - 4(1)(3)} }{2(1)}  

x = \frac{-5 \pm \sqrt{25 - 12} }{2}  

x = \frac{-5 \pm \sqrt{13} }{2}  

x = \frac{-5 \pm 3.61 }{2}  

x = \frac{-5 + 3.61 }{2}, x = \frac{-5 - 3.61 }{2}

x=-0.695 \ \textgreater \ \ \textgreater \  -0.7, x= -4.305 \ \textgreater \ \ \textgreater \ x=-4.31

Therefore, the solutions to the quadratic equation  are x = -0.7 and x = -4.31. Hope this helped and have a phenomenal day!

Your answer is 4.31
