We are given the price if each ticket, the amount raised, and how many tickets that the STUDENTS sold. So we know that Children tickets cost $3 and adult tickets cost $5, and we also know that they raised $1025. If the students sold 275 tickets, we can assume that these tickets sold by the students where sold TO other students, meaning that we would take 275x3=825 and then use that for 1025-825=200 then use that for 200/5=40 so in total, 40 adult tickets where sold and 275 children tickets where sold. 275+40=315 tickets sold
