A paper folding machine folds fliers at a rate of 15 per minute, with 90% of the fliers folded accurately. With this information, what is the fewest number of minutes Kenton should set as the machine's run time if he needs 3000 fliers folded accurately and the timer can be set only for a whole number of minutes?

I came up with 3333/90% = 3,000 so then 3333/15 = 222. Is the answer 222?
