Answer: 81 of each type of ticket was sold
Step-by-step explanation:
81 × adult tickets ($7) = $ 561
81 × students ticket ($4)= $324
Answer:
Adult ticket were sold = 97 tickets
Student tickets were sold = 53 tickets
Step-by-step explanation:
Let x be the adult ticket and y be the student ticket.
Adult ticket for $7.
Student ticket for $4.
Total sold ticket = 150
Total sold tickets for $891
Solution:
As per given statement, 150 tickets were sold for $891.
So, total adult ticket and student ticket is equal to 150 tickets:
[tex]x+y=150[/tex] ------------(1)
Adult tickets for a school musical sold $7 and student tickets sold for $4.
So, the equation is written as:
[tex]7x+4y=891[/tex] ------------(2)
Solve the equation 1 for x.
[tex]x = 150-y[/tex] ---------------(3)
Substitute [tex]x = 150-y[/tex] in equation 2.
[tex]7(150-y)+4y=891[/tex]
[tex]1050-7y+4y=891[/tex]
[tex]1050-3y=891[/tex]
Add 3y both side of the equation.
[tex]1050-3y+3y=891+3y[/tex]
[tex]1050=891+3y[/tex]
[tex]3y=1050-891[/tex]
[tex]3y=159[/tex]
[tex]y=\frac{159}{3}[/tex]
y = 53 student tickets
Substitute y = 53 in equation 3.
[tex]x=150-53[/tex]
x = 97 adult tickets
Therefore, 97 adult tickets and 53 student tickets were sold.
