We can see that Henry(H) makes a flat fee of 125. Therefore, he will have a +125 on his equation. The only one that does this is A. As you can see, it models all of our given information perfectly.
so the way I did this was by adding how much he works per week which is 35 per week. so he works 70 hours in 2 weeks. he earns 10 dollars per hour. so 10 times 70 you get 700 but he spends 50. so 700 minus 50. you get 650. he has 650 dollars left.
