If Mary drives 250 miles, option A is $10 more expensive than option B.
For 150 miles, both options cost the same, and if she drives less than this amount, option A costs less.
Mary wants to rent a car for a day and has 2 options: Option A and Option B. For each pricing option, the cost (in dollars) depends on miles driven, as shown in the graphic.
To know the most expensive option when Mary drives 250 miles, we need to locate the point of each plot for 250 miles and find the value of y (cost).
- For Option A, the cost is $90.
- For Option B, the cost is $80.
The difference between both options is
$90 - $80 = $10
If we want to know for what number of miles for which both options cost the same, we have to locate the intersection between both lines, which occurs at 150 miles.
If Mary drives less than 150 miles, option A (red plot) costs less.
If Mary drives 250 miles, option A is $10 more expensive than option B.
