Jillian’s school is selling tickets for a play. The tickets cost $10.50 for adults and $3.75 for students. The ticket sales for opening night totaled $2071.50. The equation 10.50 a plus 3.75 b equals 2071.50, where a is the number of adult tickets sold and b is the number of student tickets sold, can be used to find the number of adult and student tickets. If 82 students attended, how may adult tickets were sold?
so given that adult ticket (a) cost $10,50 and student ticket (b) cost $3,75 ,the total ticket sales was $2071,50 ,given again that attended 82 students so 10,50a +3,75b = 2071,50 how you think what mean this : given again that attended 82 students ?
