Okay, so in this next scenario here, we have another weight loss problem.
00:06
So april is losing, is on a diet right now.
00:10
And the first week of her diet, she loses five pounds.
00:13
And over the next three weeks, she loses three more pounds, she gains two pounds, and then loses one.
00:19
And we're trying to find how much weight or her total change over the four weeks.
00:25
So first let's start with, by defining our initial amount here.
00:29
So let's define again our initial as zero.
00:32
So this is april's starting weight.
00:35
And if we add weight, we're going to add weight.
00:38
So we go in the positive direction.
00:40
And if we lose weight, we will go in the negative direction.
00:44
So the first week, april loses five pounds...
