Question

Please Help!!!!! You have twice as many nickels as pennies. you have $1.10. how many of each coin do you have? Solve each problem using a system of equations.

Answer 1

Explanation:

n=2p

p+5n=110, using n found above makes this become

p+5(2p)=110

p+10p=110

11p=110

p=10, since n=2p

n=2(10)

n=20

So there are 10 pennies and 20 nickels.
