Ответ:
The function of company A.
Step-by-step explanation:
For a linear equation:
y = a*x + b
the rate of change is "a", the coefficient that is multiplicating the variable.
Now, for company A we know that:
There is a fixed fee of $50, and $150 for each day.
So if you rent the car for x days, the total cost will be:
y = $150*x + $50
Then for this company, the rate of change is $150.
For company B we have the function:
y = $50*(2x + 1)
Where again, x is the number of days that you rent the car.
We can rewrite this as:
y = $50*2*x + $50*1
y = $100*X + $50
In this case, the rate of change is $100
Then the company with a great rate of change is the function for company A.
