A deck has a cost of $9.80 per square foot to construct. If the deck has an area of 390 square feet, then complete the following calculation that computes the total construction cost of the deck. Show how units
cancel, and make sure that you have units in your final answer.
(390 sq. ft.)
$9.80
sq. ft.

4.0 ft

yes

i don't see any

step-by-step explanation:

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
