The question is incomplete. The complete question is :
Nate starts a lawn-mowing business. In his business, he has expenses and revenue. Nate's expenses are the cost of the lawn mower and gas, and his revenue is $25 per lawn. At what point will Nate's revenue exceed his expense?
Cost of lawn mower = $ 200
Cost of gasoline = $ 2 per lawn
Solution :
Given :
Cost of the lawn mower = $ 200
The cost of gasoline expense for one lawn = $ 2
The revenue generated for one lawn = $ 25
So let the number of lawn to be mowed = x
Therefore the total expenses = 
So, the total revenue = 
The point for which the revenue will exceed the total expenditure will be :

So at 
Thus the revenue exceeds the total expenditure after mowing 9 number of lawns.
If the shapes are similar, the correspondent sides are in proportion:

Let's plug the values and solve for x:

Multiply both sides by x to get

The only feasible solution, though, is
, because it wouldn't make sense to have negative lengths.
The percentage increase in the area of a rectangle is 44% if each of its sides is increased by 20%.
<h3>What is a rectangle?</h3>
It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.
It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
New length = (120x/100) m
New breadth = (120y/100) m
New area = (6x/5 × 6y/5) m²
The difference between the original area = xy
new area 36xy/25
Percentage increase = (11xy/25 1/xy x 100)
= 44%
Thus, the percentage increase in the area of a rectangle is 44% if each of its sides is increased by 20%.
