A Broadway theater has 700 seats, divided into orchestra, main, and balcony seating. Orchestra seats sell for $50, main seats for $40, and balcony seats for $25. If all the seats are sold, the gross revenue to the theater is $26,400. If all the main and balcony seats are sold, but only half the orchestra seats are sold, the gross revenue
is $22,900. How many are there of each kind of seat?

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this

step-by-step explanation:

the answer is a if my teacher taught me correct

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
