#1 f

Let's find the profit when 20 tiles are sold. So in this case, x=20


Start with the given function.


Plug in . In other words, replace each x with 20.


Evaluate to get 400.


Multiply -1 and 400 to get -400


Multiply 56 and 20 to get 1120


Now combine like terms


So when 20 tiles are sold, the profit is $420


#1 g



Let's find the profit when 25 tiles are sold. So in this case, x=25



Start with the given function.


Plug in . In other words, replace each x with 25.


Evaluate to get 625.


Multiply -1 and 625 to get -625


Multiply 56 and 25 to get 1400


Now combine like terms



So when 25 tiles are sold, the profit is $475



#1 h


Let's find the profit when 0 tiles are sold. So in this case, x=0



Start with the given function.


Plug in . In other words, replace each x with 0.


Evaluate to get 0.


Multiply -1 and 0 to get 0


Multiply 56 and 0 to get 0


Now combine like terms


So when 0 tiles are sold, the profit is -$300


In other words, the company lost $300 by not selling any tiles
