Calculators are sold to students for 20 dollars each. Three hundred students are willing to buy them at that price. For every 5

dollar increase in price, there are 30 fewer students willing to buy the calculator. Let x the number of times the price is increased and let R stand for revenue.
At the maximum revenue, the actual selling price will be $

If you increase the price 9 times which is 5 dollars more each time you get only 30 students that are willing to buy it. Any more increases will lead to no one wanting to buy it.

Answer:

The answer is $35.

Step-by-step explanation:

If you do the process, you will get $35. First, put in the calculator 20 x 300 to get 6000. Now for each time after this, add five dollars to the price of the calculators and subtract 30 students from the total number of students. You will notice that any price after $35 decreases from a revenue of $7,350. So therefore, the answer is $35.

If U = { 1 , 2 , 3 , 4 , 5 ,6 , 7 , 8 , 9 }. A={1 , 2 , 3 , 4 } , B= {2 , 4 , 6 , 8 } .Find
Zina [86]

Answer:

(A - B)' = {2, 4, 5, 6, 7, 8, 9}

(A n B) = {2, 4}

Step-by-step explanation:

Given the set :

U = { 1 , 2 , 3 , 4 , 5 ,6 , 7 , 8 , 9 }

A={1 , 2 , 3 , 4 } , B= {2 , 4 , 6 , 8 }

(A - B) = elements of A which are not in B

(A - B) = {1, 3}

(A - B)' = the complement of A - B ; element in the universal set which are not in A - B

(A - B)' = {2, 4, 5, 6, 7, 8, 9}

(A n B) = elements in both set A and set B

(A n B) = {2, 4}

Help me solve # 15 & 16
makkiz [27]

Answer:

15) C=frac{5}{9}(F-32)

16) 12 hours

Step-by-step explanation:

15) F=\frac{9}{5}C+32 \\F-32 = \frac{9}{5}C\\\frac{5}{9}(F-32)=C

16) If Jim drove 168 mi in 4 hours, this means it takes him

\frac{4 hours }{168 mi}

this many hours to drive 1 mile. So if we multiply this by 504 mi:

\frac{4 hours }{168 mi} 504 mi = 4 \cdot 3 hours = 12 hours

As the earth rotates, it travels a distance of 80 miles in 5 minutes. At this constant rate, which equation best represents y, t
solniwko [45]

Answer:

y=16x

Step-by-step explanation:

So, you are given the equation as if y=total distance the earth travels in x minutes. If you are given that you travel 80 miles in 5 minutes, you can plug  these value into the variables they are representing and solve for the constant.

Visual:

y=xk          y=miles        x=minutes         k=constant

Plug in your values and you get:

80=5k

Now, you solve for k by diving 5 on both sides, which leaves you with k=16.

Now you plug your value for k into the original equation, leaving you with y=16x
