Step-by-step explanation:

Let p(x) be the profit function.

\therefore \: p(x) = r(x) - c(x) \\  = 6.5x -( 0.75x + 1850) \\ = 6.5x - 0.75x  -  1850  \\ \purple{ \boxed{ \bold{ \therefore \: p(x)  = 5.75x - 1850}}} \\  this \: is \: the \: profit \: function. \\ \\ p(500) = 5.75 \times 500 - 1850 \\  = 2875 - 1850 \\  p(500) = 1025 \\  \\ p(1000) = 5.75 \times 1000 - 1850 \\  = 5750 - 1850 \\  p(1000) = 3900 \\  \\ p(5000) = 5.75 \times 5000 - 1850 \\  = 28750 - 1850 \\  p(5000) = 26900

Answer:

First, we are going to find the sum of their age. To do that we are going to add the age of Eli, the age Freda, and the age of Geoff:


The combined age of Eli, Freda, and Geoff is 40, so the denominator of each ratio will be 40.


Next, we are going to multiply the ratio between the age of the person and their combined age by £800:

For Eli: 

For Freda: 

For Geoff: 


We can conclude that Eli will get £180, Freda will get £260, and Geoff will get £360.

To fit between two windows, the width of a bookshelf must be no greater than feet. Mrs. Aguilar purchases a bookshelf that is 77
kozerog [31]
Given:
width of bookshelf no greater than 6 1/2 feet
purchased bookshelf that is 77 inches wide

We need to find the equivalent value in feet of the purchased bookshelf.

1 foot is equal to 12 inches

77 inches * 1 foot/12 inches = 77 ft/12 = 6 5/6 ft

Or we can convert the feet into inches:

6 1/2 feet convert to improper fraction.

((6*2)+1)/2 = 13/2 feet

13/2 ft * 12 inches/1ft = (13 * 12)/2 = 156/2 = 78 inches

Compare the maximum width of 78 inches to the actual width of 77 inches. 

The purchased bookshelf can fit between two windows.

I think of a number. I multiply it by 7. I add 12. The result is 40. What is the number I am thinking of?​
julia-pushkina [17]
The number that you are thinking of is 4. To get this answer I did the opposite of how you received your answer.
40 - 12 = 28
28 ÷ 4 = 7
The number that you are thinking of is 4.
