1 The admission fee at a small fair is $1.50 for children and $4.00 for adults. On a certain day, 2,200 people enter the fair and $5,050 is collected. Which of the following systems of equations would represent this scenario?
A a + c = 2,200 1.5a + 4c = 5,050

B a + c = 5,050 1.5a + 4c = 2,200

C a + c = 2,200 4a + 1.5c = 5,050

D a + c = 5,050 4a + 1.5c = 2,200
