Answer: The correct answer is C. 11
Step-by-step explanation: To determine how many more hours Scott can work this week, we need to subtract the hours he has already worked from the maximum number of hours he can work in a week.
Maximum number of hours Scott can work in a week = 20 hours
Hours he has already worked:
Monday: 2 hours
Tuesday: 4 hours
Wednesday: 3 hours
Total hours he has already worked = 2 + 4 + 3 = 9 hours
To find the remaining hours he can work, subtract the total hours he has already worked from the maximum number of hours he can work:
Remaining hours = Maximum hours - Total hours already worked
Remaining hours = 20 - 9 = 11 hours
Therefore, Scott can work 11 more hours this week.
