<u>Given</u>:
The given expression is 
We need to determine the equivalent expression.
<u>Equivalent expression:</u>
The equivalent expression can be determined by simplifying the given expression.
Thus, let us factor out the common term "mn" from the denominator.
Thus, we have;

Cancelling the common terms, we get;

Thus, the equivalent expression is 
Hence, Option c is the correct answer.
the answer is going to be -1
Adult ticket = x
student ticket = y
<span>An adult ticket costs twice as much as a student ticket.
</span>x = 2y
Total earnings is $1040
64x + 132y = 1040
x = 2y ------------------------------ (1)
64x + 132y = 1040 -------------(2)
Sub (1) into (2)
64 (2y) + 132y = 1040
128y + 132y = 1040
260y = 1040
y = 4 ------- sub into (1)
x = 2(4) = 8
Student ticket = $4
Adult ticket = $8
