So Maurice would have 2N nickels
Total number of coins is N + 2N + 9 = 3N + 9
Each nickel is 5 pennies
3N of nickels = 15N pennies
-----------
Their worth is 84 cents
15N + 9 = 84
15N = 75
N = 75/15 = 5
N = 5
This means Nina has 5 nickels.
Given:
weight of mixture : 1792 ounces
output of mixture : 560 bars of soap

1792 oz / 560 bars = 3.2 ounces per bar.
