Your answer would be 36,000 because he gets 3000 every month and every month for a year he would get your answer which would be 3000×12 which equals 36,000
Answer: He is not correct.
Steps:
Let x1 and x2 be the first and second number, respectively.
![x_2 = \frac{5}{4}x_1\\\frac{4}{5}x_2 =x_1](https://tex.z-dn.net/?f=x_2%20%3D%20%5Cfrac%7B5%7D%7B4%7Dx_1%5C%5C%5Cfrac%7B4%7D%7B5%7Dx_2%20%3Dx_1)
In words, if the second is 125%, or 5/4 of the first number (first equation),
then the first is 4/5 of the second, which is 0.8 or 80%.
Your answer would be 8 Hammond per minute. Hope this helps!
