For a production of sweeney todd in las vegas, orchestra seats cost $42 and mezzanine seats cost $25. if a group of 14 people sh
Lesechka [4]

Answer: 8 orchestra seats and 6 mezzanine seats.

Step-by-step explanation:

Let be "o" the number of orchestra seats they bought and "m" the number of mezzanine seats they bought.

Set up a system of equations:

\left \{ {{42o+25m=486} \atop {o+m=14}} \right.

You can apply the Substittution Method to solve the system of equations:

1. Solve for "o" from the second equation:

o=14-m

2. Substitute it into the first equation and solve for "m":

42(14-m)+25m=486\\\\588-42m+25m=486\\\\-17m=-102\\\\m=\frac{-102}{-17}\\\\m=6

3. Substitute the value of "m" into o=14-m and evaluate, in order to find the value of "o". This is:

o=14-6\\\\o=8
