Need

a stadium has 49,000 seats. seats sell for $30 in section a, $24 in section b, and $18 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 $1,246,800 from each sold-out event. how many seats does each section hold?

Step-by-step explanation:

Since the number of A seats equals the total of the rest of the seats, it is half the seats in the stadium: 49000/2 = 24,500.

The revenue from those seats is, ...

  24,500×$30 = $735,000

so the revenue from B and C seats is ...

  $1,246,800 -735,000 = $511,800

__

We can let "b" represent the number of B seats. Then there are 24500-b seats in the C section and the revenue from those two sections is ...

  24b +18(24500-b) = 511800

  6b = 70,800 . . . . . . . . . . . . . . . subtract 441000, collect terms

  b = 70,800/6 = 11,800 . . . . . . . seats in B section

  24,500 -11,800 = 12,700 . . . . . seats in C section

There are 24500 seats in Section A, 11800 seats in Section B, and 12700 seats in Section C.

the one that has a slope of 1/2 and is positive.

step-by-step explanation: 2 buckets 1 trip ; 4 buckets 2 trips and so on.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
