First of all, we know that you make $300000 per year, so you will make $300000÷365≈$822 per day(round this to the nearest one) because 1 year has 365 days if you don't count as leap years. Then, we also know that one week has 7 days, so you will make 822*7≈$5754 per week
Or
We know that one years has 52 weeks, so you will make $300000÷52≈$5769/week. Hope it help!
