A small plant manufactures riding lawn mowers. The plant has fixed cost (leases, insurance, etc.) of $48,000 per day and variable cost (labor, materials, etc.) of $1,400 per unit produced. The mowers are sold for $1,800 each. So the cost and revenue equations are

y= 48,000 + 1,400x
y= 1,800x

The break-even point is the point where cost = revenue

1800x= 48000+1400x
X= 120
The equilibrium quantity is 120 mowers

cost= 4800 + 1400x

x= 120

To find the breakeven point for this plant, you need to determine the number of units at which the cost and revenue equations are equal.

The cost equation is given as:
C(x) = 48,000 + 1,400x

The revenue equation is given as:
R(x) = 1,800x

To find the breakeven point, set the cost equation equal to the revenue equation and solve for x:

48,000 + 1,400x = 1,800x

To solve this equation, isolate the variable terms:
48,000 = 1,800x - 1,400x

Combine like terms:
48,000 = 400x

Divide both sides by 400:
x = 48,000 / 400
x = 120

Therefore, the breakeven point occurs when the plant produces and sells 120 riding lawn mowers.
