And here are the potential answers…
- 00:27
It wants us to find the percent of Emily’s 2000 calorie intake that she ate...
- 00:32
which means we only care about the number of calories she consumed,
- 00:36
not the amount of fat in her Macchiato. So we can just throw that out.
- 00:40
Now, to calculate a percent, we just divide our amount by the total, and multiply by 100.
- 00:45
In this case, the total is 2000 calories, and our amount is the number of calories in
- 00:49
a chocolate chunk and grande caramel macchiato.
- 00:52
We’re given that the macchiato has 240 calories,
- 00:55
and the chocolate chunk, according to the table, has 360 calories.
- 01:00
Add them. So 240 plus 360 gives us 600 calories.
- 01:05
Then just take 600 divided by 2000, we get .3.
- 01:09
Then multiply it by 100, we see that, these two food items, when consumed together...
- 01:14
...tell us that Emily has had 30% of her daily calorie intake.
- 01:19
The answer's D.

Which will be roughly the shape of Emily’s belly if she keeps up her current dietary habits…
