A baker has three canisters of flour in her supply room. Canister a can hold 30 pounds, canister b can hold 45 pounds, and canister c can hold 60 pounds

30 x 3 = 90 45 x 2 = 90

Step-by-step explanation:

you times 30 x 3 = 90 and 45 x 2 = 90

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
