A certain theather has 100 balcony seats- For every $2 increase in the price of a balcony seat above $ 10, 5 fewer seats will be solved. If all the balcony seats are sold when the price of each seat is $ 10, what is the price of a balcony seat if total revenue from the sale is $ 1360?

The answer is $12- can you pls explain?

Are you sure its 12? 12 * 95 = 1140

I got 16.

Like it or not, Under these situations, the fastest way is to plug in..Even without answer choices , it took me just under a minute.

if you wish to use an equation

(10 + x) (100-y) = 1360

It still makes sense to plug in 2 ,5 ...4,10 and 6,15 ...

i will try to solve this equation if you want.

thanks
