Question 250009: Penny collected some change in preparation for a garage sale. She collected two more nickles than twice the number of dimes and eight fewer quarters than twice the number of nickles. If the value of the quarters was $1.60 greater than four times the value of the nickles and dimes together, what was the total value of the change that Penny collected? Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! the hard part of these coin problems is setting up the equations
for every variable (unknown) we need another equation
so if we have 3 unknowns we need 3 equations
let n= nickels
q=quarters
d=dimes
n=2d+2
2n-8=q
25q=160+4(5n+10d)
let me know what you get
