Question

Niko has a collection of 60 stamps. Of these stamps, 30% are from New York, 25% are from California, and the rest are from countries outside of the United States. How many stamps in Niko’s collection are from countries that are outside of the United States?

Answer 1

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
