Dime Collection
How many coins of each type are in the collection?
A collection of 50 coins is worth $5.20. There are 12 more nickels than dimes, and the rest of the coins are quarters. How many coins of each type are in the collection?
28 nickels, 12 dimes, and 10 quarters
26 nickels, 14 dimes, and 10 quarters
26 nickels, 10 dimes, and 14 quarters
10 nickels, 14 dimes, and 26 quarters
Think it out… There are 12 more nickels than dimes. There is only one of your choices that has 12 more nickels than dimes.
In case no one taught you this shortcut, you only need to look at the last digit of the number.
Example: 28 nickels, 12 dimes
Only look at the last digit – 8 nickels, 2 dimes. You have 6 more nickels than dimes. You are suposed to have 2 more (looking at the last digit). That ain’t right.
