Final answer:
To find the percentage of money saved in December, divide the amount saved in December by the total amount saved and multiply by 100. In this case, the percentage is 20%.
Step-by-step explanation:
To find the percent of the total amount of money Micah saved during the month of December, we need to divide the amount he saved in December ($600) by the total amount he saved last year ($3000) and then multiply by 100 to get the percentage.
The calculation would be:
Percentage = (Amount saved in December / Total amount saved) x 100
Percentage = ($600 / $3000) x 100
Percentage = 0.20 x 100
Percentage = 20%
