Dan has $ 46. He bought some candy bar for $ 24 each one costing $ 1. How many candy bar did he buy?
Dan has $46. 
He buys candy bars for $24. 
Each candy bar costs $1. 

How many candy bars did he buy? 

We can solve this problem by using division. We know that he has $46, and we know that he spent $24 on candy bars. So if we divide $24 by $46, we will know how many candy bars he bought. 

$24/$46 = x 

We can solve for x by using inverse operations. In this case, we will divide both sides by $24$. 

$24/$46 = x 
$24/x = 46$ 
$1/x = 46/24$ 
$x = 24/46$ 

We can simplify this fraction by dividing both the numerator and the denominator by 2. 

$x = 12/23$ 

This means that Dan bought 12 candy bars.
