let


a = the number of adult tickets sold


c = the number of child tickets sold


On Saturday,173 tickets were sold:


a + c = 173


for a total sales of $1376.40:


9.30a + 6.20c = 1376.40


by solving the system of equations:


a + c = 173


9.30a + 6.20c = 1376.40


we find:


a = 98 adult tickets
