Question

illian’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 10.50a + 3.75b = 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?

Answer 1

There was 168 adults because once you times 3.75 by 82 you get 307.50 then subtract 307.50-2071.50=1764 then divide that by 10.50 by 1764 and you get 168
