The answer to Part a is $44,800. I did this by 40000*2*3/50 which comes out to 4,800 you add that to your beginning worth, 40,000. Part b is as follows; 9,600 which comes out to be $49,600. Replace the 2 in the original equation to be 40,000*4*3/50. The number '2' and '4' represent the years, and the 3/50 is equal to 6%. 6% in math terms is 3/50. The answer to part c is as follows; 40000*10*3/50 which comes out to be 24,000 so your final answer for part c is: $64,000 I hope this helped! Let me know if you need more work shown, and I'll add more! :)
Answer:
x = 3/2 or x = -4
Step-by-step explanation:
The identifiable error the students have is that before the left hand side of the equation is factorized, the right hand side value of 12 ought to be brought to the left hand side, leaving a net value of zero on the right hand side. Then whatever is factored on the left hand side is then equated to zero and then we can find the two values of x after setting each of the individual factors to zero
We proceed as follows;

Answer:
(2,3)
