Q:
Jack has a collection of new nickels and quarters. He has a total of 50 coins worth $10.30. How many of each coin does he have?
Accepted Solution
A:
Let q represent the number of quarters Jack has. Then his collection value is ...
25q +5(50 -q) = 1030
20q = 780
q = 780/20 = 39
Jack has 39 quarters and 11 nickels.
