Answer:

<h2>The price should be either $3 or $20.</h2>

Step-by-step explanation:

The relationship between the number of calculators sold, x and the price p is given by two equations. R reffers the revenue of the company.

  1. x = 2300 - 100p.
  2. R = xp or, 6000 = xp or, x = \frac{6000}{p}.

Now, <u>putting the value of the second equation in first equation</u>, we get

x = 2300 - 100p\\\frac{6000}{p} = 2300 - 100p\\60 = 23p - p^{2} \\p^{2} - 23p + 60 = 0\\p^{2} - 20p - 3p + 60 = 0\\(p - 20)(p - 3) = 0.\\p = 20, 3.

The price is either $3 or $20.

X^2 + y^2 = 8<br> X-y=0<br> Select all of the following that are solutions to the system shown
ludmilkaskok [199]

X^2 + y^2 = 8
X-y=0 so x = y

replace x = y into X^2 + y^2 = 8

y^2 + y^2 = 8

2y^2 = 8

y^2 = 8/2

y^2 = 4

y = - 2 and y = 2

because x = y

so x = - 2 and x = 2

solutions:

x= - 2 and x = + 2

y= - 2 and y = + 2
