Answer:
7 hours
Step-by-step explanation:
First find the total number of hours she practices based on the average of 2 hours a day for six days.
This means 6*2 = 12 , she practices a total of 12 hours.
Next find the total hours she already practiced. She practices 1 hour a day from Mon to Fri, which is 5 days, so 1*5 = 5 hours. This is the hours she practiced already.
To meet the mean, she needs to practice 12-5 = 7 hours more on Saturday.

Because it gives you a number that is close to the answer and if it is close to your number like for instance, the actual answer is 10 then if you get 5 as your estimate that's close.
