Which set of ordered pairs is made up of points on the graph of the function below?
y = -3x + 8

a. 

(-1,11), (0,8), (1,5), (2,2)

  b. 

(11,-1), (8,0), (5,1), (2,2)

  c. 

(11,-1), (8,0), (1,5), (2,2)

  d. 

(-1,11), (8,0), (1,5), (2,2)

lets not say how long i've been stuck on this question

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
