Jennifer has a collection of 1,600 coins. Of the coins, 40% are dated before 1940, 35% are dated from 1940 to 1980, and the rest are dated after 1980. How many coins in Jennifer’s collection are dated after 1980?

40% + 35 % = 80 %    so 20% are dated after 1980

20% is .20 in decimal form

 

.20 (1600) = 320 coins dated after 1980
