Question 999601: a coin bank contains pennies, nickels and quarters. there are seven times as many nicked as pennies and three times as many quarters as pennies. the total amount of money in the bank is $5.55. find the number of pennies, nickels and quarters in the bank

You can put this solution on YOUR website!
p = number of pennies
n = number of nickels
d = number of dimes


n = 7p
q = 3p
p + 5n + 25q = 555

Write everything in terms of p.

p + 5(7p) + 25(3p) = 555
111p = 555
p = 5

There are 5 pennies, 35 nickels, and 15 quarters.
