<pre>
Your equation is this

50n + 300 = n*80 - 150.   (*)   (written in cents !)

The left part is described by these sentences: "Casper bought some pencils at 50 cents each. He had 3 dollars after the purchase."

The right part is this sentence: "If he wanted to buy the same number of note pads at 80 cents each, he would be short $1.50."

Now solve equation (*).

300 + 150 = 80n - 50n,   or

30n = 450,

n = {{{450/30}}} = 15.

<U>Answer</U>. Thus you found that the number of pencils is 15.
