 <translate> The cost of laundering all of Leo’s trousers is 10 * 9 = 90 dollars. Since the total bill was 140 dollars, this means that all the shirts were cleaned for 140 - 90 = 50 dollars. As each shirt is cleaned at 5 dollars, Sudsy Laundry therefore laundered a total of 50 / 5 = 10 shirts. The missing shirts are therefore 10 - 2 = 8 shirts.
Therefore, the answer is 8. <yor> Owó tó máa náni láti fọ gbogbo aṣọ Leo ni 10 * 9 = 90 dọ́là.
