(-3) + (1) + = -2 or ....2 pounds lost for the first 2 weeks

So for the rest of the 11 days she lost 2 pounds....2*11 = 22 pounds

now add the 2 pounds she lost to this total for 24 pounds all together

good for her.

She lost 3 pounds on her first week. Then gained one pound on her second, so after 2 weeks, she has lost a total of 2 pounds.

After the first two weeks, there are 11 weeks left in the diet. If she loses 2 pounds each week for 11 weeks, that means she loses a total of 2*11 or 22 pounds.

Add those together and she lost a total of 24 pounds across all 13 weeks.
