Explanation: 54 yards is about 162 feet, and since we are converting measurements we need this ( duh ) and 135 seconds is approximately 2.25 minutes, so what we need to do is is divide the numbers like any conversion problem: 162 divided by 2.25  is 72. 
Hope this answer helps!
 
        
             
        
        
        
Answer:
   $68.97
Step-by-step explanation:
Markup is the difference between the cost of an item and the price at which it is sold:
   cost price + markup = selling price
Here, the markup is said to be 70%. The base for that percentage can be either the cost price or the selling price. The way this question is worded suggests the markup is 70% of the cost price.
So, we have ...
   cost price + 0.70 × cost price = selling price
or
   cost price × (1 + 0.70) = selling price
__
Then, to find the cost price, we can divide by its coefficient in this equation. Doing that gives ...
   cost price = (selling price)/1.70
   cost price = $117.25/1.70 = $68.97
The store's purchase price before the markup for this item was $68.97.
