Answer:

3b - r  

Step-by-step explanation:

b + g + y = r

g = 2b, so

b + 2b + y = r

Combine like terms

3b + y= r

Subtract 3b from each side

y = 3b - r

The number of yellow balloons was 3b - r.

Answer:

612 adults

361 students

Step-by-step explanation:

To solve this question, set two equations:

Let x be number of adults and y be number of students.

As there are in total 937 people, the equation would be the sum of both adults and children:

x+y=937

x=937-y  ...... ( 1 )

As the total sale amount is $1109, the equation would be to add up the ticket fee:

2x+0.75y=1,109  ...... ( 2 )

Put ( 1 ) into ( 2 ):

2(937-y)+0.75y=1,109

1874-2y+0.75y=1,109

-1.25y=-765

y=763/1.25

y=612

Put y into ( 1 ):

x=973-612

x=361

Therefore there are 612 adults and 361 students.
