Answer: 27

Explanation: If we add 30% and 25%, a total of 55% of his stamps come from within the United States. To figure out what percent come from outside the United States, you can subtract 55% from 100% to get 45%. Finally, we need to figure out how many stamps that is, so 45% or 60 stamps is:

0.45 x 60 = 27 stamps
