For this case we have the following equation:
 30x = 48 + 22x
 An example of real life is:
 "Laura earns $ 30 per hour at her job, Maria earns 22 dollars per hour at her job plus 48 $ of fixed salary, find the number of hours for which both get the same profit"
 In the given equation,
 x: represents the time in hours.
        
             
        
        
        
Step-by-step explanation:
The total expenses stay the same at $92,039.
The income changes to 12,000 × $35 = $420,000.
So the profit is $420,000 − $92,039 = $327,961.
 
        
             
        
        
        
Answer:
agree with both because 1 dollar = 4 muffins so 2 x 4 = 8 muffins and 4x4 = 16 muffins
  
        
             
        
        
        
Answer:
Frank
Step-by-step explanation:
First let's start by calculating the speed of each runner. 
Let's use feet per second
Frank's speed is already given in feet per second: 14 feet/second
We are given that Jake runs 382 feet in 38 seconds. To bring this down to feet/second we need to divide both numbers by 38. 
382/38=10.05 feet/second (about)
We are given that Will runs 1 mile in 394 seconds. 1 mile is equivalent to 5280 feet. Now we divide both numbers by 394 to bring it down to feet/second. 
5280/394=13.401  feet/second (about)
We are given that Ron runs 555 feet in 1 minute. 1 minute is equivalent to 60 seconds. Now we divide both numbers by 60 to bring it down to feet/second. 
555/60=9.25 feet/second 
After comparing all the speeds, we can conclude that Frank runs the fastest
