Answer:
P(x) = 3x -150
Step-by-step explanation:
Substitute the given functions in to the profit equation.
P(x) = R(x) - C(x)
P(x) = (5x) - (2x +150)
P(x) = 5x -2x -150 . . . . eliminate parentheses using the distributive property
P(x) = 3x -150 . . . . . . . collect terms
It is possible to list more than 5 decimal numbers between 4.78 and 4.79.
The list is:
4.781
4.782
4.783
4.784
4.785
4.786
4.787
4.788
4.789
3 8/15
2 1/5 + 1 1/3 = 3 8/15
x +0y+0z = 400
-x +y+0z = 150
-8x +0y +z = 250
The last column is the solution
The rest of the columns are the coefficients of the variables
