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.

25q +5(50 -q) = 1030

20q = 780

q = 780/20 = 39

Jack has 39 quarters and 11 nickels.
