Colin gets x gbp wages each week. after he pays his tax of t gbp ,he then pays his rent of 120. he shares whats left between himself and his wife. how much do they get each?

what statement? is there an image?

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
