You have a handfull of loonies and quarters in your hand. In total, there are 20 coins and the value of all of these coins equals $14.75. How many loonies and how many quarters do you have?

You have 13 loonies and 7 quarters.

Step-by-step explanation:

Given that you have a handfull of loonies and quarters in your hand, and in total, there are 20 coins and the value of all of these coins equals $ 14.75, to determine how many loonies and how many quarters do you have the following calculation must be done:

Loonie = 1

Quarter = 0.25

1 - 0.25 = 0.75

20 x 0.25 = 5

14.75 - 5 = 9.75

9.75 / 0.75 = 13

13 x 1 + 7 x 0.25 = X

13 + 1.75 = X

14.75 = X

Therefore, you have 13 loonies and 7 quarters.
