Answer:

Option B. 220

Step-by-step explanation:

Let

x ----> the number of student tickets sold

y ----> the number of adult tickets sold

we know that

$x+y=360$

$y=360-x$ ----> equation A

$3x+5y=1,360$ ----> equation B

Solve the system by substitution

substitute equation A in equation B

$3x+5(360-x)=1,360$

solve for x

$3x+1,800-5x=1,360$

$5x-3x=1,800-1,360$

$2x=440$

$x=220\ student\ tickets$
