Jason has five coins in his pocket: a penny, a nickel, a dime, a quarter, and a half-dollar. how many different sums of money can be formed using exactly three of the coins?

 10

Step-by-step explanation:

Given : Jason has five coins in his pocket: a penny, a nickel, a dime, a quarter, and a half-dollar.

Since each coin has different value from others.

So the combination of any 3 coin will give a different amount.

We know that the combination of r things out of n things =

Therefore , the combination of 3 coins out of 5 =

Hence, the number of different sums of money can be formed using exactly three of the coins = 10

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
