So,
All you have to do is find the total labor cost and put it over the revenue.
We have two workers each earning $8/hr. (lousy), and they work 40 hrs./week.
2 * $8 = $16/hr.
$16/hr. * 40 hrs. = $640

Cross out zeros.

Simplify.



Convert the denominator to 100.


=
32%
The labor cost is 32% of the revenue.
To get the answer you would subtract 11% from 100%, getting the answer 89%.
B. Total number of times the activity is performed: Number of times an event occurs
Answer:
30 CDs and 10 Videos were sold.
Step-by-step explanation:
Given that a used book store also started selling used CDs and videos. In the first week, the store sold 40 used CDs and videos, at 4.00 per CD and 6.00 per video.
The sales for both CDs and videos totaled to 180.00.
Let CDs be x and Videos be y
Then we have x+y =3040
and 4x+6y = 180
Two simultaneous equations in two variables and can be solved by elimination method
multiply I equation by 4 and subtract from II.
2y = 20
y =10
x = 30
30 CDs and 10 Videos were sold.
Answer:
The area of the region is 25,351
.
Step-by-step explanation:
The Fundamental Theorem of Calculus:<em> if </em>
<em> is a continuous function on </em>
<em>, then</em>

where

A function
is an antiderivative of the function
if

The theorem relates differential and integral calculus, and tells us how we can find the area under a curve using antidifferentiation.
To find the area of the region between the graph of the function
and the x-axis on the interval [-6, 6] you must:
Apply the Fundamental Theorem of Calculus
