Okay so for the first one all you have to do is divide 4.90 by 2.5 and get 1.96. So your answer for the first on is $1.96.
For the second one you just have to divide 416 by 13 and you get 32. So each friend gets 32 crayons.
Hope this helped you (;

Answer:
The two values of x are 20 and 60
Step-by-step explanation:
Given;
cost function: C = 60x + 300
revenue function: R = 100x − 0.5x²
Profit = R - C
300 = 100x − 0.5x² - ( 60x + 300)
300 = 100x − 0.5x² - 60x - 300
300 + 300 = 100x − 0.5x² - 60x
600 = 40x - 0.5x²
600 = 40x - ¹/₂x²
multiply both sides by 2
1200 = 80x - x²
re-write the equation
80x - x² = 1200
-x² + 80x - 1200 = 0
multiply through by (-1)
x² - 80x + 1200 = 0
factorize the quadratic equation
x² (- 60x - 20x) + 1200 = 0
x² - 60x - 20x + 1200 = 0
x(x - 60) -20(x - 60) = 0
(x - 20)(x - 60) = 0
x - 20 = 0 or x - 60 = 0
x = 20 or 60
Therefore, the two values of x are 20 and 60
