Julian'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 is a 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 many adult tickets were sold?

Respuesta :

okay. 82 students attended. multiply 82 by 3.75. 82×3.75=307.5. subtract 307.5 from 2071.5. 2071.5-307.5=1764. then you divide 1764 by 10.50. 1764÷10.50=168. 168 adult tickets were sold.
