Answer:
Mark sold 268 adult tickets.
Step-by-step explanation:
We are given the following in the question.
Let x be the number of students ticket sold and y be the number of adult tickets sold.
Total number of tickets sold = 445
Thus, we can write the equation:
[tex]x + y = 445[/tex]
Cost of student ticket = $3
Cost of an adult ticket = $5
Total income = $1871
Thus, we can write the equation:
[tex]3x + 5y = 1871[/tex]
Solving the two equations, we get,
[tex]3x + 5y - (3x+3y) = 1871 - 3(445) \\2y = 536\\\Rightarrow y = 268\\\Rightarrow x = 445 - 268 = 177[/tex]
Thus, Mark sold 268 adult tickets.
