Multiplication Word problem

Question

Each day, Sarah sells 6 boxes of cookies for the Girl Scouts New Year fundraiser. How many boxes does she sell in 15 days?

Answer 1

Hi Judith,

 

There are two ways to look at this.  

 

You could make a chart with days and number of boxes sold

1st day    6 boxes

2nd day   6 boxes

3rd day    6 boxes

.

.

.

14th day    6 boxes

15th day    6 boxes.

 

Adding the number of boxes sold each day you would have 6+6+6+6+6+6+6+6+6+6+6+6+6+6+6  = 90 boxes

 

But that is tedious, and is the reason we invented multiplication.

 

Instead you just multiply the number of boxes sold each day  TIMES the number of days of selling.

 

This would give you 6 * 15 = 90 boxes
