Question

Phoebe put her hand in her pocket and pulled out 60 cents. How many different ways could this amount be made using 19c, 20c, and 50c coins?

Answer 1

There are four different ways to make 60 cents using 19c, 20c, and 50c coins.

Step-by-step explanation:

To find the number of different ways to make 60 cents using 19c, 20c, and 50c coins, we need to consider different combinations of the coins.

Let's start with the 50c coin. If we use one 50c coin, we would need to make up the remaining 10 cents using 19c and 20c coins. There are two possible combinations: one 50c coin and one 10c coin, or one 50c coin and two 5c coins.

If we don't use a 50c coin, we can use 19c coins to make up the 60 cents. We can have one 19c coin and two 20c coins, or three 20c coins.

Therefore, there are a total of four different ways to make 60 cents using 19c, 20c, and 50c coins.
