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 , 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:

168 adult adult ticket were sold

Explanation:

Hello

The tickets cost for adults is $10.50

The tickets cost for students is $3.75

number of adult ticket sold: A

number of student ticket sold: B

10.50A+3.75B=2071.50 Equation 1

B=82 Equation 2

replacing equation 2 in equation 1

10.50A+3.75(82)=2071.50

10.50A=2071.50-307.50


A=(1764)/(10.50) \\\\A=168\\\\\\

168 adult adult ticket were sold

Have a great day.
