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? 168 adult tickets

Step-by-step explanation:

10.5a + 3.75b = 2071.50

b = 82 students

Substitute 'b' value in the equation

10.5a + 3.75 * 82 = 2071.50

10.5a + 307.5 = 2071.50

10.5a = 2071.50 - 307.5

10.5a = 1764

Divide both sides by 10.5

a = 1764/10.5

a =17640/105

a= 168

168 adult tickets were sold
