The admission fee at the fair is $1.50 for children and $4 for adults. On a certain day, 2,200 people enter the fair and $5,050 is collected. How many children attended? How many adults attended?
children = 750, adults = 1,000
children = 1,000, adults = 700
children = 1,300, adults = 750
children = 1,500, adults = 700
