Answer:
The function that can be used in the online shopping club about its monthly revenue is:
![R = -400x^{2} +7200x+70000](https://tex.z-dn.net/?f=R%20%3D%20-400x%5E%7B2%7D%20%2B7200x%2B70000)
Step-by-step explanation:
First, we're gonna take into account the different values we have in the exercise:
- 10,000 members
- $7 per month for membership
- Loses of 400 members by each $1 monthly increase
How the variable
represents the price increase, we can do the formula below:
In this formula, we represent in the first part that by each 1 in the variable
, the total of members will be reduced in 400, in the second part, we mention that at the same time, the membership fee will be increased in the same value of
. Now we must simplify this function:
We operate the values:
Solve we can:
And organize:
At the end, how
represents the monthly revenue received by the club, we use that variable for our formula:
Your answer will x= 5y/3-25/3
Answer:
y = 2x+5
Step-by-step explanation:
Add y on both sides, this cancels out the y on the left side
add 2x and add 5 on both sides, this cancels out the -2x and the -5 on the left side.
<u>OR </u>
Divide/Multiply both sides by -1, as it will cancel out the negatives as two negatives make a positive.
If you needed a value for y, more info is needed.
hope this helps (:
please rate, thanks !
So we convert both to improper fractions.
38/7 and 1/16
Now we make them the same denominator
608/112 and 7/112
Now we divide 608 by 7
Maximum amount which can be given is 85 scholars.
