Answer:

B) The equation <em>x </em><em>+ </em><em> (2 x + 40)  + (3 x - 50)   =  15,002 </em> represents this scenario suitable.

Step-by-step explanation:

Let x represent the number of  upper-level seats.

Total seats in stadium = 15,002

Now, seats in the lower level =  3 ( Seats in upper level ) - 50

= 3x - 50

or, the total seats in the lower level = (3 x - 50)

Also,  seats in the middle level =  2 ( Seats in upper level ) + 40

= 2x + 40

or, the total seats in the middle level = (2 x + 40)

Now, according to question

Upper Level seats + Middle level seats + Lower level  = Total seats

⇒ (x) +  (2 x + 40)  + (3 x - 50)   =  15,002 seats

Hence, the equation <em>x </em><em>+ </em><em> (2 x + 40)  + (3 x - 50)   =  15,002 </em> represents this scenario suitable.

Weiming, Joyce and Siti divide cookies to sell in a ratio of 5: 12: 9. After Weiming sold 28 cookies, the ratio becomes 1: 8: 6.
Strike441 [17]

Answer:

216 cookies

Step-by-step explanation:

From the question,

Let the total cookies in the first place be x cookies.

Their ratio = 5:12:9

Total  = 5+12+9 = 26.

Weiming share = (5/26)x = 5x/26

If weiming sold 28 cookies

⇒ (5x/26)-28

⇒ (5x-728)/28

Hence Weiming new share = (5x-728)/28 cookies

The new ratio is 1:8:6

The total cookies becomes = x-28

Therefore,

(1/15)(x-28) = (5x-728)/28

(x-28)/15 = (5x-728)/28

Crossmultiply

28(x-28) = 15(5x-728)

28x-784 = 75x-10920

Collect like terms

28x-75x = -10920+784

-47x = -10136

x = -10136/-47

x = 215.7

x ≈ 216 cookies
