Full price of popcorn: $3.50 
Price of popcorn after half the movie: $1.75
price of drinks: $1.35 
The question is....."Determine the cost for purchasing 3 orders of popcorn and 3 drinks when the movie is half over." 
$1.75*3=$5.25
$1.35*3=$4.05
the price of the 3 orders of popcorn would be $5.25 
The price of the 3 orders of drink would be $4.05 
5.25 + 4.05 = $9.30 
In total the 3 orders of popcorn and 3 orders of drink would cost $9.30
Hope this helps! :) 
        
                    
             
        
        
        
Answer:
Cooper made $22.80 per hour.
Step-by-step explanation:
Since Cooper made a total of $228.00 within 10 hours, the money he made each hour is equivalent to the rate of change. That means that in order to get the amount of money made in one hour, you must first turn the ten hours into one using division. Since you divided ten into one using division, you divide the $228.00 by ten using division. 
228 divided by 10 is 22.8, therefore Cooper is making $22.80 per hour.
