Based on a linear equation, for three hours of lawnmowing service, the service provider will charge $35.00.
The total charges for lawn mowing are determined using a linear equation of the slope intercept.
The equation is written as y = mx + b, where m is the slope of the line and b is the intercept, with x and y represent representing the input and output variables, respectively.
y = mx + b
m = $5
x = 3 hours
b = $20
Therefore, y = $35 (5 x 3 + 20)
Thus, we can conclude that the service provider will charge $35 for 3 hours of lawnmowing service.
