Answer:
a)
And we want to find a function:
We can find the slope with this formula:
And then we can use the point to find the intercept
and we got:
So then the linear function is given by:
b) For this case we have that m = 475 so we can replace into the function to find the cost like this:
And for the other case we have a cost of 155 and we want to find the number of miles associated so we can do this:
Step-by-step explanation:
For this case we can define the following notation:
m= represent the miles travelled
C= represent the cost
Part a
For this case we have the following two points given:
And we want to find a function:
We can find the slope with this formula:
And then we can use the point to find the intercept
and we got:
So then the linear function is given by:
Part b
For this case we have that m = 475 so we can replace into the function to find the cost like this:
And for the other case we have a cost of 155 and we want to find the number of miles associated so we can do this:
