B.1,500 children and 700 adults
C. 1,650 children and 550 adults
D. 550 children and 1,650 adults

B . 1500 children and 700 adults

Step-by-step explanation:

create an equation

make use of variables:

children --x

adults --y

1.5x + 4y = 5050

x + y = 2200

now make use of the options given and place them into the equation .

lets try the first one

1.5 * (700) + 4*(1500) = 7050

lets try the second one

1.5 * ( 1500) + 4 *(700) = 5050

the answer is B.

you can check the others if you want to , so that you are able to see if you are correct. ( optional)

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
