Question
The cost of renting a landscaping tractor is a $150 security deposit plus the hourly rate is $30/hour. Write the function f that represents the cost of renting the tractor.
- f(x) = 150x + 30
- f(x) = 150 - 30x
- f(x) = 150 + 30x
- f(x) = 30x - 150
Hint:
Find total cost for the tractor and add security deposit.
The correct answer is: f(x) = 150 + 30x
Given That:
The cost of renting a landscaping tractor is a $150 security deposit plus the hourly rate is $30/hour. Write the function f that represents the cost of renting the tractor.
>>> Let the tractor is taken for x hours.
>>> Hourly rate per hour = $30
>>> Total cost = security deposit + cost per hour 
number of hours.
>>>>Therefore, the required function is 30x + 150.
The security deposit is constant that is 150 dollars and the total cost for the tractor is 30x.
>>>Then, the functional representation of the given data is 150 + 30x.
