Question

There are some nickels, dimes, and quarters in a large piggy bank. For every 2 nickels, there are 3 dimes. For every 2 dimes, there are 5 quarters. There are 500 coins in all. How many nickels, dimes, and quarters are in the piggy bank? How much are the coins in the piggy bank worth all together?

Answer 1

n represents the number of nickles

1.5n represents the number of dimes

(2.5)(1.5n) represents the number of quarters

 

n + 1.5n + 3.75n = 500

 

Can you solve for n and answer?
