Answer:
For this case we want to test if the the average monthly income of all students at college is at least $2000. Since the alternative hypothesis can't have an equal sign thne the correct system of hypothesis for this case are:
Null hypothesis (H0): 
Alternative hypothesis (H1): 
And in order to test this hypothesis we can use a one sample t or z test in order to verify if the true mean is at least 200 or no

Answer:
19.65 left
Step-by-step explanation:
The total amount that he has is 3 * 12 =                   36 dollars.
From this he buys a CD for                          15.00
There is a 9% tax on 15 dollars 15*9/100 =   <u> 1.35</u>
Amount spent =                                                        <u> 16.35</u>
Amount left                                                                19.65
 
        
                    
             
        
        
        
The equation is Y= 2x + 4
