The equation that represents profit is $40x - $20. 
The profit after 5 days in business is $180. 
The profit after 10 days in business is $380. 
The profit after 10 days in business if revenue is $45 is $430. 
<h3>What is profit? </h3>
Profit is total revenue less total cost. 
Profit = total revenue - total cost 
Profit = $40x - $20 
Where: 
x = number of days
<h3>What is the total profit after 5 days and 10 days? </h3>
$40(5) - $20
 = $200 - $20 
= $180
$40(10) - $20 
$400 - $20 
$380
<h3>What is total profit if revenue is $45? </h3>
$45(10) - $20 
= $450 - $20 
= $430

Answer:
 two of the sides are 21 m long and one of the sides is 28 m long 
 
        
             
        
        
        
-2x < = 3x + 1 < = 10
split them
-2x < = 3x + 1         3x + 1 < = 10
-2x - 3x < = 1          3x < = 10 - 1
-5x < = 1                 3x < = 9
x > = -1/5                 x < = 3
solution is : -1/5 < = x < = 3 <==
