taxi cab charged $3.60 for all rides and $2.20 per mile. If Tommy’s cab ride cost $43.20, how many miles did he travel?

Answers

Answer: 18 miles

Step-by-step explanation: Cabs drivers fee is 3.60 for all rides so you subtract that from 43.20 and you get 39.60 and divide that by the amount he costs per mile and you get 39.60 divided by 2.20 and get 18.

Answer:

Tommy travels 18 miles in total

Step-by-step Explanation:

43.20 - IV (IV = Initial value)

43.20 - 3.60 = 39.6

39.6/ROC (ROC = Rate of Change)

39.6/2.2 = 18
