Problem Name: FEED THE ANIMALS

 

Grade Level:  3-5                                                               Content Area:  Numbers, Systems and Relations

 

Problem Solution:

 

Part A -

 

$25 + $15 = $40

 

Part A:  To find the amount needed to feed the animals for one day, add          

$25 plus $15. 

           

             $40 x $14 = $560

 

To find the cost for two weeks, multiply $40 times 14 days.

(Students may solve this using repeated addition.)

 

            Part B –

 

            $933 ¸ $40 = 23 days

 

The find the number of days the animals could be fed, divide the amount donated by the cost per day.  The remainder of $13 tells how much money was left over. 

(Students may solve this using repeated subtraction.)
