The value of my coins if i have p pennies, n nickels and twice as many quarters as pennies.

0.06p+0.05n

Step-by-step explanation:

p=number of pennies

n=number of nickels

q=number of quarters

You know pennies are worth $0.01, nickels are worth $0.05, and quarters are worth $0.25.

You have twice as many quarters are pennies, so you have 2p quarters.

The value of your coins are: 0.01p+0.05n+0.25(2p)= 0.01p+0.05n+0.5p = 0.06p+0.05n where p is the number of pennies and n is the number of nickels.

Hope this helps!
