Answer:
b
Step-by-step explanation:
90×(2)

each mile is equal to 90 calories
therefore 2 miles is equal to 180
The total cost that a customer should incur in its dealings with company A should be,
c = 50t + 100
For company B
c = 60t + 80
Equating these two charges
c = 50t + 100 = 60t + 80
Thus, the answer is the fourth choice.
