Step-by-step explanation:
Let's represent the number of mochas bought with the variable  , and the number of lattes bought with the variable
, and the number of lattes bought with the variable  .
.
Since there are  students, the total number of mochas and lattes bought must be
 students, the total number of mochas and lattes bought must be  . This can be represented with the following equation:
. This can be represented with the following equation:

We can also set up another equation based on the total amount spent on the coffe:

If we rearrange the first equation, we can solve for  :
:

If we substitute this into the second equation, we can solve for  :
:





Subtituting this back into the original equation, we can solve for  :
:



Therefore, 9 mochas and 14 lattes were bought.
 
        
                    
             
        
        
        
The answer would be -18°F at 6AM
Hope this helps ?(:

Answer: 3 years
Because:
1 year=1050
2years=525
3years=262.5
        
             
        
        
        
F(x)=x(3x+5)
or
f(x)=3x²+5x
Here the domain in general is: -∞<x<∞
But the length of the rectangle cannot be negative, therefore the domain is all real numbers greater than zero.
Option D is correct.
