Answer: D. Taxi B is the better deal for the first 7.5 miles
Explanation:
In the given graph,
Miles is independent variable and cost is the dependent variable,
And, Line A shows the cost in different miles of taxi A and line B shows the cost in different miles of taxi B.
Since, the lines A and B intersect at 7.5 miles,
Therefore, for 7.5 miles, the cost of taxi A and Taxi B are equal.
But, The initial cost of taxi A is greater than that of taxi B.
⇒ Before, 7.5 miles the cost of taxi A is greater than that of taxi B.
⇒ Before, 7.5 miles the cost of taxi B is less than that of taxi A
⇒ For a costumer, taxi B will be less expensive than that of taxi A for first 7.5 miles.
Option D is correct.
