Answer:
500
Step-by-step explanation:
Let x be the original price
Take the first discount
x - 18 percent
x - .18x = new price
x( 1-.18)
x ( .82) = new price
Now we take a 20 percent discount
This is on the discounted price, use .82x
.82x - 20 percent= 2nd discounted price
.82x - .20(.82x)
.82x -.164x
.656x= 2nd discounted price
.656x = 328
Divide each side by.656
.656x/.656 = 328/.656
x =500
The original price was 500
So I'm assuming that you're taking Calculus.
The first thing you want to do is take the integral of f(x)...
Use the power rule to get:
4X^2-13X+3.
Now solve for X when f(x)=0. This is because when the slope is 0, it is either a minimum or a maximum(I'm assuming you know this)
Now you get X=0.25 and X=3. Since we are working in the interval of (1,4), we can ignore 0.25
Thus our potential X values for max and min are X=1,X=4,X=3(You don't want to forget the ends of the bounds!)
Plugging these value in for f(x), we get
f(1)=2.833
f(3)=-8.5
f(4)=1.667
Thus X=1 is the max and X=3 is the min.
So max:(1,2.833)
min:(3,-8.5)
Hope this helps!
He moved the decimal to the right 4 times. He should of moved it to the right 2 times. Giving him 0.15%
Store one has 15 rolls for 3.60 so divide it answer will be .24 per roll. store 2 has 18 rolls for 3.80. divide it up answer is .21 per roll. so store 2 is the answer.
Area A Output: 2, 4, 6, 8
Perimeter P Output: 6, 8, 10, 12
Explanation: Just replace the x with the inputs and then solve.
