Question 496994: Directions: Express the given quantity in terms of the indicated variable.
Question: The value (in cents) of the change in a purse that contains twice as many nickels as pennies, four more dimes than nickles, and as many quarters as dimes and nickles combined; p = number of pennies.
am i on the right track by saying
let n= nickels
p= pennies
d= dimes
q= quarters
2n+p
4d+n
q= d+n .....i know the answer should only have the variable "p", but i don't see how to make it an algebraic equation only using "p". thank you

Twice as many nickels as pennies:
n=2p
Four more dimes as nickels
d=n+4
as many quarters as dimes and nickles
q=d+n
Solve all for p
n=2p;p=1/2n
d=n+4;d=2p+4
q=(2p+4)+2p=4p+4..
