#### Worksheet Overview

A farmer has some cows that he milks every day.

Each cow produces 4 pints of milk a day.

How much milk does each cow produce in 4 days?

First, let's look at the important information.

We know that each cow produces 4 pints of milk a day.

We know that we need to find the total after 4 days.

To find the answer, we need to calculate  4 + 4 + 4 + 4  = 16 ( 4 x 4 = 16 )

Each cow produces 16 pints of milk after 4 days.

If the same farmer has 100 cows, how much milk do they produce in total after 1 day?

First, let's look at the important information.

We know the farmer has 100 cows.

We know they produce 4 pints each a day.

We know we need to find the total after 1 day.

To find the answer we need to calculate 100 (cows) x 4 (pints each)

100 + 100 + 100 + 100 = 400  ( 100 x 4 = 400 )

The farmer will have 400 pints of milk after one day.

If the same farmer sells 10 of his cows, how many cows will he have left?

First, let's look at the important information.

We know he had 100 cows.

We know he sells 10 of them.

To find the answer we need to calculate 100 - 10 ( 10 less than 100 )

100 - 10 = 90

The farmer will have 90 cows left.
