Selma reached into a coin jar, randomly pulled out 100 coins, and found that 20 of them were nickels. If the jar originally contained 250 coins, what would be a reasonable estimate for the total number of nickels originally in the jar before Selma took any out?

math 
Ms. Sue,
20/100 = x/250
100x = 5000
x = 50
