A certain theater has 100 balcony seats. For every $2 increase in the price of a balcony seat above $10, 5 fewer seats will be sold. If all the balcony seats are sold when the price of each seat is $10, which of the following could be the price of a balcony seat if the revenue from the sale of balcony seats is $1,360?

(10+2n)(100-5n)=1360

n=3 or 12, so the price can be $16 or $34

The trick is you can view the $2 increase and five seat decrease as the same, instead of representing them as two seperate variables.
