Peter rode in a taxi to get to college. The initial fee for a taxi ride is $3.80. Each mile traveled costs an additional $4.50. The total cost of his taxi ride was $12.80. Let x represent the number of miles Peter rode in the taxi. Which of the following equations represents this situation? 4.50x + 12.80 = 3.80 4.50x + 3.80 = 12.80 3.80x + 12.80 = 4.50 3.80x + 4.50 = 12.80 None of the above
