In that situation, you use the information you DO have.  It's not always 
enough to do the job.  But often it is, and in that case, you use what you 
do have to answer the question or solve the problem.
Sadly, I can't be any more specific than that.  You haven't told us what 
information you do have ... only what information you don't have. 
        
             
        
        
        
We have been given that Marcus works for 26 hours each week and 48 weeks each year.
Thus in a year he works for  hours.
 hours.
Now, we have been given that Marcus earns $8.40 per hour. 
Therefore, in 1248 hours, he earns

Marcus has to pay tax if he earns more than $10,000. Now we have calculated that he earns $ 10483.2  which is higher than $10,000.
Therefore, Marcus has to to pat tax.

36.00 will be enough to pay for fuel because if you multiply the 8.8 gallons of diesel needed by the fuel cost per gallon you get 35.112
        
                    
             
        
        
        
Answer:
a. Infinitely many solutions
Step-by-step explanation:
The given equations are  2x - y = 3
4x = 6 + 2y
We can use substitution method to solve these system of equations.
2x - y = 3
y = 2x - 3
Now plug in y = 2x - 3 in the second equation, we get
4x = 6 + 2(2x - 3)
4x = 6 + 4x  - 6
4x = 4x
Here we get infinitely many solution.
Both the equations are the same.
Thank you.
