So first you need to know 1/20=3/x to get x we need to multiply 3 by 20 . which equals 60 so 1/20 of 60 is 3 .answer is 60

Quadratic Equation Applications
serious [3.7K]

The number of $0.50 increases to maximize the profit is X = 1.

First of all, we need to write the linear function which represents the price of the ticket for each increase of $0.50:

P - Price of each ticket.

x - number of increases.

We know that the current price is $5.00, so:

    P(x) = 0.5x + 5.00

After that, let's build a linear function which shows the number of tickets sold <u>for each</u> price increase:

    T - number of tickets.

    x - number of increases.  

    T(x) = -100x + 1200

With all this done, we can finally build the quadratic function which represents the money earned:

M - money earned

M = Tickets Sold \times TicketPrice\\\\M = T(x) \times P(x)\\\\M = (0.5x + 5) \times (-100x + 1200)\\\\M = -50x^{2}  + 600x -500x + 6000\\\\M(x) = -50x^{2}  + 100x + 6000\\\\

Now, to finish, we only have to <u>calculate the value of X</u>(number of increases) which can give us the maximum value of this function:

the X coordinate for the maximum value of a quadratic is expressed by:

   Xmax = \frac{-b}{2a} \\\\

In our equation, b = 100 and a = - 50 :

Xmax = \frac{-(100)}{2(-50)} \\\\Xmax = \frac{-100}{-100} \\\\Xmax = 1

Thus, the number of increases which <u>maximizes</u> the profit is 1.

Who created multiplication ?
Anuta_ua [19.1K]

Multiplication is a very old concept in math. So old that it dates back to ancient egypt, mesopotamia, etc. Each place probably came up with the concept on their own parallel to one another, or trade helped make the concept spread. It's very likely that the actual person who came up with the idea is unknown and won't be known since the concept is so ancient. It's like asking "who came up with the alphabet" which is an equally old concept.

Side note: multiplication is repeated addition. So if we added 3+3+3+3+3 to get 15, then we can say 3*5 = 12 as a shortcut. So its likely ancient peoples were adding the same number to itself over and over, leading them to develop a shortcut notation/method to get the answer quicker.
