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 + 3.750 = 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?

    Explanation:

    10.5a+3.75b=2071.5

    b=82

    10.5a+3.75*82=2071.5

    10.5a = 2071.5 - 307.5

    10.5a = 1764

    a = 1764/10.5

    a = 168 adult tickets
