Answer 1

The total change in Jim's weight over four weeks is a loss of 16 pounds, calculated by summing his weekly weight changes.

Step-by-step explanation:

The question involves calculating the total change in weight over a four-week period for an individual named Jim, who is on a diet. Jim lost 5 pounds in the first week. In the following weeks, he had a series of gains and losses: he lost 7 pounds, gained 3 pounds, and then lost another 7 pounds. To find the total change in weight, we sum up these values: -5 (loss) + (-7 loss) + 3 (gain) + (-7 loss) = -16. Therefore, the net change in his weight over the four weeks is a loss of 16 pounds.
