I have a question about below problem:
Hot dog vendors sold an average of 66 hot dogs per stand. Trainee vendors averaged 70 hot dogs sold. The ratio of non-trainee vendors to trainee vendors was 1 : 2. What was the average number of hot dogs sold by the non-trainee vendors?
The solution I have assumes there's 1 NT and 2 T.
2 T means it's 2 x 70hot dogs = 140 hot dogs.
An average of 66 dogs with 3 people means: total hot dogs sold = 66 * 3 = 198
=> The one NT sold 198 - 140 = 58.
Is there a different approach to this where I can use the ration algebraically ? Even if it's slower, I'm just curious since I wouldn't have though of using the average to get a total.

NT : T = 1 : 2
For every 3 hot dog vendors, 1 is a non-trainee vendor, and 2 are trainee vendors. Introduce 'n' = average number of hot dogs sold by the non-trainee vendors.
The total number of hotdogs must be equal to the number of hotdogs sold by the non-trainee vendors and the trainee vendors.
1 x n + 2 x 70 = 3 x 66
n + 140 = 198
n = 58

You've probably already done it algebrically but in a conceptual manner!
