(1) Matthew bought four floor seats and three balcony seats for $82.50.
Let the cost of a floor seat be x and a balcony seat be y.
4x + 3y = 82.50
Using this equation we cannot clearly tell the value 1 floor seat
and 1 balcony seat which Jake must pay for. Hence, insufficient.

(2) Linda bought eight floor seats and six balcony seats for $165.00.
Let the cost of a floor seat be x and a balcony seat be y.
8x + 6y = 165
Using this equation we cannot clearly tell the value 1 floor seat
and 1 balcony seat which Jake must pay for. Hence, insufficient

On combining the statements, we have 2 equations and 2 unknowns.
However it is not possible to get a unique value because the equations are
dependent on each other
. Hence, insufficient(Option E)
