Tina lost 3 pounds on the first week of her diet. She gained a pound on the second week, and then lost 2 pounds a week during every week afterwards. She has been dieting for a total of 13 weeks. How many pounds has Tina lost in all?

A. 22 pounds
B. 24 pounds
C. 20 pounds
D. 26 pounds

I answered B, because she has been dieting for a total of 13 weeks. She lost 3 pds the first week and she gained 1pd the second week. She lost 2pds regularly for 11 additional weeks. 3pds-1pd=2pds 11 weeks x 2pds=22pds+2pds=24pds

24 looks good to me.

Your answer is correct! Tina lost 3 pounds in the first week and gained 1 pound in the second week, resulting in a net loss of 2 pounds. From the third week onwards, she consistently lost 2 pounds per week for 11 weeks.

To calculate the total weight loss, you can add up the amount of weight lost each week: 2 pounds (from the first two weeks) + 2 pounds per week (for the next 11 weeks) = 24 pounds.

So, Tina has lost a total of 24 pounds. Therefore, the correct answer is B.
