Hello! remember you have to write complete questions in order to get good and exact answers. Here I'll explain this in a general way assuming the following table:
As you can see, x increases in steps of 1 units. So let's check the difference in y:
So we have a constant difference and we can conclude the table represents a line. Since the line passes through then y is directly proportional to x, so we can write:
Then:
Finally, the equation of the line is:
Answer:
The required expression for total cost:
The cost for renting car for 2 days and driving 70 miles is $51.88
Step-by-step explanation:
Consider the table shown below which repented the required options.
Car Rental Prices :
Option 1 Option 2
$19.99 per day $50 fee
$0.17 per mi $0.17
Let d represents the number of days and m represents the number of miles.
you rent a car using option 1, For d days and m miles.
The required expression for total cost:
Find the cost for renting car for 2 days and driving 70 miles
Substitute d=2 and m=70 in above expression.
Hence, the cost for renting car for 2 days and driving 70 miles is $51.88
