Answer:

Step-by-step explanation:
The functions for cost and revenue are given below:

The profit will be maximized at its <u>line of symmetry,</u>
<u />
From P(x), a=-13.85, b=1939
<u>Line of symmetry,</u>
<u />
<u />
<u>The maximum profit that can be made will occur when x=70</u>
<u />
<u />
The maximum profit that can be made form the sales of the oven is $12,465.
Note: I am not 100% sure that this is the correct way to solve this problem. It is just my best attempt to help.
Keep in mind that every percentage can be made into a decimal. 12% = 0.12 because 12% is also 12/100 as a fraction.
Since a percentage is the original number multiplied by the percent, you can solve this problem by dividing the number given by the percent. Be sure to turn the percent into a decimal to make it easier. Your work should look like this:
12% = 0.12
1,000 / 0.12 = 8,333.33
That is the first step. How you have to finish the problem and find what 88% is. To do this, you can simply multiply 88%, or 0.88, times the answer you get in the first part. Your work should look like this:
88% = 0.88
0.88 * 8,333.33 = 7,333.33
Now to check your work, you can add 7,333.33 and 1,000 to see if it equal the total of 8,333.33
7,333.33 + 1,000 = 8,333.3
Since it is equal, this is your answer.
Answer: B
Step-by-step explanation: 7/8 * 3 = 2 5/8 :)
Answer:
Heres how:
Step-by-step explanation:
Example, 7.831 , here you can see that there are 3 numbers relating to a decimal. the 1 by itself is 0.1000, 3 by itself is 0.300, and the 8 by itself is 0.80 . If you add this, you get 0.831. now add the whole number, Seven. if there is more digits in the decimal, then just add another zero.
Step-by-step explanation:
0x<3
x>3/0
x>∞
x is undefined.
