Answer:
When doing square roots the opposite is squaring so, to find one that is more than 12 and less that 13 would be finding one that is in between √144 and √169
That leaves your answer as √150, because it is more than √144 (which is 12) and less than √169 (which is 13)
B √150

11 ⅓ gallons.
Explanation:
Since she sold 3⅓ gallons more on Sunday than she did on Saturday, you need to add 10⅔+3⅓. ⅓+⅔=3/3, or 1. 10+3=13, and 13+1=14. She sold 14 gallons on Sunday.
On Monday, she sold 2⅔ less than she did on Sunday, so we need to do 14-2⅔. 14-2 is 12, and 12-⅔= 11⅓. This means that she sold 11⅓ gallons on Monday.
Hope this helps :)
