The St. Mark's Community Barbecue served 250 dinners. A child's plate cost \$3.50 and an adult's plate cost \$7.00. A total of \$1347.50 was collected. How many of each type of plate was served? Is the answer 125 for child and 125 for adult is this correct?

• ALGEBRA 1 A -

250=C+A
3.5C+7A=1347.50
3.5(250-A)+7A=
3.5A=472.5
A= 135
