Here’s your shmoop du jour, brought to you by Chocolate Chunk Cookies.

00:06

A great way to cleanse the palate after downing a box of Mint Milanos.

00:10

Emily ate a Chocolate Chunk cookie and drank a Grande <<GRAHN-day>> Caramel

00:14

Macchiato <<MOCK-ee-ah-toe>>, which has 240 calories and 7 grams of fat.

00:18

What percent of her recommended daily intake of 2000 calories did she consume?

00:23

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.

01:20

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