Problema Solution
in his coin bank, Joe has 3 times as many quarters as nickles. if the value of the quarters is $5.60 more than the value of the nickles, how many of each kind does he have?
Answer provided by our tutors
let 'x' represent the number of nickels, then '3x' represents the number of quarters
5.60 = 0.25(3x) - 0.05(x)
solving for 'x' we have x=8
3*8 = 24
Joe has 8 nickels and 24 quarters
