The admission fee at a small fair is $1.50 for children and $4.00 for adults. On a certain day, 2200 people enter the fair and $5050 is collected. Write the system of equations for this scenario if a is the number of adults and c is the number of children.

1.50c + 4.00a = 5050

c + a = 2200

4c + 1.50a = 5050

C + a = 2200

1.50c + 4.00a = 2200

C + a = 5050

4.00c + 1.50 a = 2200

C + a = 5050
