A store selling art supplies finds that they can sell x sketch pads each week at a price of p dollars each, according to the formula x = 1000 − 400 p. What price should they charge (in interval notation and rounded to the nearest cent) if they want to sell

a . At least 625 pads each week? b . More than 300 pads each week?

c . Less than 200 pads each week? d . At most 475 pads each week?

Answers

Answer:

c and b and a

Step-by-step explanation:

The store should charge a price between ($0, $0.94] to sell at least 625 pads each week. The store should charge a price between ($0, $1.75) to sell more than 300 pads each week. The store should charge a price between ($2.00, $2.50) to sell less than 200 pads each week. The store should charge a price between [$1.31, $2.50) to sell at most 475 pads each week.

a)

In order to solve part a of the problem, we need to set our equation as an inequality. Part a asks us to find the price the store should charge to sell at least 625 pads each week. The word at least gives us a clue on what symbol to use. In this case we should use the [tex]\leq[/tex] symbol, like this:

[tex]625\leq 1000-400p[/tex]

and now we can solve the inequality, we can start by switching places between the 625 and the 400p so we get:

[tex]400p\leq 1000-625[/tex]

[tex]400p\leq 375[/tex]

and we divide both sides into 400, so we get:

[tex]p\leq \frac{375}{400}[/tex]

[tex]p\leq $0.94[/tex]

So this can be rewritten in interval notation like this:

($0, $0.94] The price they should charge can be located between those two values.

b)

In order to solve part b of the problem, we need to set our equation as an inequality. Part b asks us to find the price the store should charge to sell at more than 300 pads each week. The word more than gives us a clue on what symbol to use. In this case we should use the < symbol, like this:

[tex]300< 1000-400p[/tex]

and now we can solve the equation, we can start by switching places between the 300 and the 400p so we get:

[tex]400p< 1000-300[/tex]

[tex]400p< 700[/tex]

and we divide both sides into 400, so we get:

[tex]p< \frac{700}{400}[/tex]

[tex]p< $1.75[/tex]

So this can be rewritten in interval notation like this:

($0, $1.75) The price they should charge can be located between those two values.

c)

In order to solve part c of the problem, we need to set our equation as an inequality. Part c asks us to find the price the store should charge to sell less than 200 pads each week. The word less than gives us a clue on what symbol to use. In this case we should use the > symbol, like this:

[tex]200> 1000-400p[/tex]

and now we can solve the inequality, we can start by switching places between the 200 and the 400p so we get:

[tex]400p> 1000-200[/tex]

[tex]400p> 800[/tex]

and we divide both sides into 400, so we get:

[tex]p> \frac{800}{400}[/tex]

[tex]p> $2.00[/tex]

at this point we need to know what the maximum price the store can charge is. We can do so by setting the equation equal to zero and solve for p, so we get:

0<1000-400p

so we can now move the 400p to the other side of the equation, so we get:

400p<1000

and divide both sides into 400 so we get:

[tex]p<\frac{1000}{400}[/tex]

which simplifies to:

p<$2.50

if the store charges more than $2.50 they will not sell any item at all.

So this can be rewritten in interval notation like this:

($2.00, $2.50) The price they should charge can be located between those two values to sell less than 200 pads each week.

d)

In order to solve part d of the problem, we need to set our equation as an inequality. Part d asks us to find the price the store should charge to sell at most 475 pads each week. The word at most gives us a clue on what symbol to use. In this case we should use the [tex]\geq[/tex] symbol, like this:

[tex]475\geq 1000-400p[/tex]

and now we can solve the inequality, we can start by switching places between the 475 and the 400p so we get:

[tex]400p\geq 1000-475[/tex]

[tex]400p\geq 525[/tex]

and we divide both sides into 400, so we get:

[tex]p\geq \frac{525}{400}[/tex]

[tex]p\geq $1.31[/tex]

So this can be rewritten in interval notation like this:

[$1.31, $2.50) The price they should charge can be located between those two values to sell 475 pads at most each week.

The radius r of the base of a cone is given by the equation r=(3Vπh)1/2, where V is the volume of the cone and h is the height of the cone. Find the radius of the paper cup to the nearest inch. Use 3.14 for π.

The radius is about

Answers

1 inch.

STEP BY STEP EXPLANATION:

We are given with the following equation r=(3V/πh)^1/2. By the picture we know that "V' is volume which translated to 5 in this problem, "π" is 3.14 and "h" is out height or 4in (in the picture we get all this values).

Therefore everything that there is left is to substitute and answer.

r = (3[5]/3.14[4])^1/2 - multiply the numbers

The stock of Company A gained 5% today to $54.60. What was the opening price of
the stock in the beginning of the day?

Answers

Answer: $51.85

Step-by-step explanation:

To find the answer, you would divide $54.60 by 100. You do that to figure out the amount of money for 1%. Then you multiply 5 to figure out 5%. Lastly, you would subtract the answer by $54.60 since your finding out how much it was at the beginning of the day. Equation: $54.60 ÷100= $.546 x 5= 2.73. 54.60- 2.75 =51.85

$51.85

To find the answer, you would divide $54.60 by 100. You do that to figure out the amount of money of 1%

Then you multiply 5 to figure out 5%. Subtract the answer by $54.60 since your finding out how much it was at the beginning of the day.

Equation: $54.60 ÷100= $.546 x 5= 2.73. 54.60- 2.75 =51.85.

Final result: $51.85
