The admission fee at the fair is $1.50 for children and $4 for adults. On a certain day, a total pf 2200 people entered the fair and $5050 in entrance fees were collected. Let c represent the number of children and let a represent the number of adults.

Choose the two equations that will create our system of equations for the story problem.

c+a=2200

1.50c+4a=5050

1.50a+4c=5050

c+a=5050

c+a=2200

Step-by-step explanation:

I did the test on K12, so if you also have the same test I promise you its correct.

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
