There are some nickels dimes and quarters in a large piggy bank for every two nickels there are 3 dimes for every two dimes that are 5 quarters there are 500 coins in total how many nickels dimes and quarters are in the piggy bank

We are given

piggy bank has nickels , dimes and quarters

Let's assume

number of nickels =n

every two nickels there are 3 dimes

so, number of dimes are

every two dimes that are 5 quarters there

so, number of quarters are

so, total number of coins = number of nickels + number of dimes +number of quarters

total number of coins =n+1.5n+3.75

there are 500 coins

so, we get

now, we can solve for n

divide both sides by 6.25

so, we get

number of dimes is 1.5n

number of quarters  is 3.75n

so,

Number of nickels =80

Number of dimes =120

Number of quarters =300............Answer
