Benny purchased a car for $19,350. The table below shows the amount of money that he still owes (y) after each payment (x) that he makes. Payment (x) Amount Owed (y) 1 $19,075 2 $18,800 3 $18,525 4 $18,250

391.6 is the correct answer

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
