Final answer:
Maddie needs to work an additional 0 0 1 2 hours to reach her goal for the week.
Step-by-step explanation:
Maddie worked 3 1 2 hours on Monday, 3 2 3 hours on Tuesday, and 2 1 4 hours on Wednesday. To find out how many more hours Maddie needs to work to reach her goal of 10 1 2 hours for the week, we can add the hours she has already worked and subtract that total from her goal.
3 1 2 + 3 2 3 + 2 1 4 = 10 1 12
To find out how many more hours she needs to work, we subtract 10 1 12 from her goal:
10 1 2 - 10 1 12 = 0 0 1 2
Maddie needs to work an additional 0 0 1 2 hours to reach her goal for the week.
