Quizplus · Accepted Answer

The cost of a cab ride can be calculated by multiplying the number of eighths of a mile traveled by $0.32 and adding $3.20. So, the equation for the cost of a cab ride in terms of the number of miles traveled would be C = 25x + 320, where x is the number of miles traveled. This equation can be derived by multiplying both sides of the original equation by 25 (since there are 8 eighths of a mile in one mile) and then adding 320 to both sides. Thus, the best choice is B.
