Answer:
At the end of the year, Travis had 9 less pounds then what he started with during the holidays, meaning that the direction of his net change in weight is negative.
Step-by-step explanation:
We don't know what Travis's weight is to start with, so let's add a variable that will substitute for his weight. It's not too important to know exactly what his weight to start with is, anyway. If you write it out using w as the weight Travis started with during the holidays, you would end up with:
w + 9 - 14 + 3 - 7
If you simplify the above equation:
w - 9
This means that at the end of the year, Travis will have 9 less pounds than what he started with in the holidays.
