Answer:
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!
