Problem Brenda’s school is selling tickets to a spring musical. On the first day of tickets sales the school sold 3 senior citizen tickets and 9 child tickets for a total of $75. The school took in $67 on the second day by selling 8 senior citizen tickets and 5 child tickets. What is the price of each senior citizen tickets and each child tickets?

Steps Equation 3x + 9y = $75 8x + 5y = $67

Equation 3x + 9y = $75 8x + 5y = $67 Answer:( Remember!!! 0 = 0 Infin. Solution 0 = # Null Set
