Astadium has 49,000 seats. seats sell for $28 in section a, $16 in section b, and $12 in section c. the number of seats in section a equals the total number of seats in sections b and c. suppose the stadium takes in $1,037,200 from each sold-out event. how many seats does each section hold?

Step-by-step explanation:

Section A seats comprise half the seats in the stadium, so revenue from those seats at a sold-out event will total ...

  $28 × 49,000/2 = $686,000

Then the remaining revenue of $1,037,200 -686,000 = $351,200 will come from some mix of B and C seats.

__

If all of the seats were C seats, the revenue would be ...

  $12 × 24,500 = $294,000

Actual revenue from those seats is $351,200 -294,000 = $57,200 more. Since each B seat contributes $4 more, there must be ...

  $57,200 / $4 = 14,300 . . . . B-section seats

Then the number of C-section seats is 24,500 -14,300 = 10,200.

There are 24,500 Section A seats, 14,300 Section B seats, and 10,200 Section C seats.

You could write 3 equations in 3 unknowns and get the same answer.

  a + b + c = 49000 . . . . . where a, b, c are numbers of seats in A, B, and C

  a - b - c = 0

  28a +16b +12c = 1037200

The solution by your favorite method is (a, b, c) = (24500, 14300, 10200), as above.

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
