Max surveyed 100 of the 200 7th graders that attend his school to help determine new lunch choices in the lunch room. he has come up with these findings which statement is best supported by the information in his graphs

answer: x=60

idk

step-by-step explanation:

payback

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
