And here's your shmoop du jour...

00:04

Marlene needs to fill a 4-gallon bucket with water from a drinking fountain.

00:08

Apparently, she started a fire that needs to be put out.

00:11

Marlene only has a jar that holds 1.5 cups.

00:14

How many trips will she need to make to the fountain?

00:17

And here are the potential answers...

00:21

Let's break down what the question is asking.

00:23

It's asking us to find the number of trips Marlene needs to make...

00:27

...but to find that number, we have to know how many cups are in a gallon.

00:31

Listen up.

00:32

There are four cups to a quart and four quarts to a gallon.

00:36

That makes 16 cups in a gallon

00:39

and 64 cups in 4 gallons. If Marlene's teensy tiny jar can hold 1.5

00:46

cups, and she needs to get 4 gallons worth of water, or 64 cups,

00:51

how many trips will she need to make?

00:54

We divide 64 by 1.5, and we get 42.6666666...and so on.

01:00

Ok, so 42.66 of Marlene's jars will carry 64 cups of water.

01:07

If Marlene makes 42 trips, then she'll only have 63 cups of water.

01:12

To make sure she has those 64 cups, she has to round up... and make 43 trip.

01:18

Our answer is E.
