Question

Priya paid $11 for two notebooks and one pack of pencils. The pack of pencils cost$4. What equation can she write to find the price of each notebook?

Answer 1

$11 for two notebooks and a pack of pencils

 

Let x be the price of one notebook

so,

 

$11 - 4$

      2

$7/2

 

x = $3.50

Answer 2

$11 = Cost of Pencil Pack + Cost of two Notebooks

 

$11 = $4 + (2 notebooks)*(Price of a notebook)

 

Let p = the price of a notebook.  The equation that Priya needs to write is:

 

$11 = $4 + 2p     

 

Now she can solve for p, the price of each notebook:

 

$7 = 2p

 

$3.50 = p
