The admission fee at a county fair is $2 for children and $4 for adults. Suppose that on the last day, 1600 people enter the fair and $5000 is collected.

Choose the two equations that can be solved as a system of equations to determine how many children and how many adults attended the fair.

a − c = 1600
4a + 2c = 5000
4a − 2c = 5000
a + c = 1600
