Use reasoning to lead to the answer of the following question:
Kendall is counting her change. She has a total of $4 in quarters, dimes, and nickels. If she has 10 quarters and 12 dimes, how many nickels does she have?

6
The total money from the quarters is 10 * $0.

25 = $2.

50.

The total money from the dimes is 12 * $0.

10 = $1.

20.

The total money from the nickels is $4 - $2.

50 - $1.

20 = $0.

30.

The number of nickels Kendall has is $0.

30 / $0.

05 = 6 nickels.

The answer: 6
