Answer:

Step-by-step explanation:
we would like to integrate the following Integral:

well, to get the constant we can consider the following Integration rule:

therefore,

recall exponent integration rule:

so let,
Thus integrate:

simplify addition:

reduce fraction:

finally we of course have to add the constant of integration:

hence,
our answer is D)
 
        
                    
             
        
        
        
3,000. You take 15,000 and multiply by .4 to get how much she spent on rent (6,000). They you subtract the rent money from her total pay to get her money that she spent on living expenses, clothes and entertainment in total (9,000). Since she spent her money in six parts (3+2+1), you divide 9,000 by 6 to get 1,500 to get each part. Since for entertainment she has two parts you multiply 1,500 by 2 to get 3,000.
