Question 323893: In a collection of coins consisting of only nickels and pennies, the total value is $1.10 and there are twice as many nickels as pennies. How many nickels are in the collection? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! let pennies be x
nickels = 2x
x+ 5*2x =110 cents
x+10x=110
11x=110
x= 10 pennies
nickels = 2x = 20
