Alberto bought his bicycle for$275. He sold for $350. What was the amount of his Percentage profit?

Step-by-step explanation:

$350 -$275= $75 profit

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees

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
