  A) a + s = 297

  B) 30a +20s = 6050

  C) 286 students

  D) 11 adults

Step-by-step explanation:

A) Total people is the sum of the numbers of adults and students:

  a + s = 297

__

B) Total revenue is the sum of revenue from each class of attendees:

  30a +20s = 6050

The solution is ...

  30a + 20(297 -a) = 6050 . . . there were 297-a students

  10a = 110 . . . . . . . . . . . . . . . . subtract 5940

  a = 11

  s = 297 -11 = 286

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
