Answer 4

how did you get 9

Answer 5

break-even point is when revenue = cost
revenue = 600x
cost = 1800 + 400x
1800+ 400x = 600x
solve for x where x is the number of barrels to be sold

Answer 6

to solve -400x from each side
1800 = 200x
to get 1*x divide by 200 keep balance divide other side as well
1800/200 = 200x/200
9 = x
