Suppose that bob places a value of $10 on a movie ticket and that lisa places a value of $7 on a movie ticket. in addition, suppose the price of a movie ticket is $5. refer to scenario 12-2. suppose the government levies a tax of $1 on each movie ticket and that, as a result, the price of a movie ticket increases to $6.00. if bob and lisa both purchase a movie ticket, what is total consumer surplus for bob and lisa?

$5.

Step-by-step explanation:

Bob and Lisa have estimated a total value of $17.

The movie tickets are actually $6 each.

$12 for two tickets.

estimated value - actual value = consumer surplus.

$17 - $12= $5

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
