A shop has a sale that offers 20% of all prices.

Nana76 [90]

<h2>Greetings!</h2>

Answer:

40% reduction

Step-by-step explanation:

To answert this, we need to find how much of the price is each percentage. This can be found my subtracting the percent from 100:

Sale price: 100 - 20 = 80

Last day price: 100 - 25 = 75

Now we need to multiply these two values together, remembering to divide both numbers by 100 first:

80 ÷ 100 = 0.8

75 ÷ 100 = 0.75

0.8 * 0.75 = 0.6

Then multiply by 100 to find the percentage:

0.6 * 100 = 60

60% is the end price, but to find the overall reduction we need to subtract this value from 100:

100 - 60 = 40

So there was a 40% reduction on the price.

I need help with the steps. The answer is (5,2)

Elden [556K]

So with this, I will be using the substitution method. With the first equation, substitute (y+3) into the x variable and solve for y:

$y+3+y=7\\2y+3=7\\2y=4\\y=2$

Next, now that we have the value of y, substitute it into either equation to solve for x:

$x+2=7\\x=5\\\\x=2+3\\x=5$

<u>And this is how you get your final answer (5,2).</u>

A college is planning to construct a rectangular parking lot on land bordered on one side by a highway. The plan is to use 440 f

NARA [144]

Let x represent side opposite to highway and y represent other two opposite sides as shown in the diagram.

The perimeter of the parking lot will be sum of 3 sides that is $x+y+y=x+2y$ .

We have been given that the plan is to use 440 feet of fencing to fence off the other three sides. This means that perimeter of 3 sides is 440.

$x+2y=440$

$x=440-2y$

We know that area of rectangle is length times width, so area of parking lot will be $A=x\cdot y$

Upon substituting value of x, we will get:

$A(y)=(440-2y)\cdot y$

$A(y)=440y-2y^2$

Now we will find the derivative of area function as:

$A'(y)=\frac{d}{dy}(440y)-\frac{d}{dy}(2y^2)$

$A'(y)=440-4y$

Let us find critical point by equating derivative to 0.

$440-4y=0$

$440=4y$

$\frac{440}{4}=\frac{4y}{4}$

$110=y$

Now we will substitute this value is equation $x=440-2y$ to solve for x as:

$x=440-2(110)$

$x=440-220=220$

Therefore, the dimensions of 220 feet by 110 feet will enclose the maximum area.
