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 $1360?
A $12
B $14
C $16
D $17
E $18
At a price of $10 each, 100 seats are sold.
For every $2 increase in the price per seat, 5 fewer seats will be sold.
The following options are implied:
12*95 = 12(100-5) = 1200-60 = 1140.
14*90 = 1260.
16*85 = 16(80+5) = 1280+80 = 1360.
In the blue option, $1360 in revenue is yielded by a seat price of $16.
The correct answer is
C.
