Answer:
he would have to work 43 hours
Step-by-step explanation:
So if we know that at job one he gets payed 860 dollars a week and in job two he gets payed 20 per hour all we need to do is divide 860 by 20 to find the number of hours in a week and it would be 43
We know what every year has 365 but once every four years has 366. We can simplify it by saying that every year has 365 and 1/4 days
Now, we just have to mulitiply

So we can say that 50 years have 18262 days and chance to 18263 (depends when we started counting)
