14,378 + 16 = 14,394
14,394 - 422 = 13,972
There were 13,972 miles on the car at the end of the second year.
You have to add the amount of miles she drove the first year with the amount of miles that were already on the car when she bought it. Then you subtract 422 since that’s the decrease in miles for the second year. When you subtract, you should get that she drove 13,972 miles in the second year.
