$29 will be their consumer surplus.
Consumer surplus is the difference between how much a consumer is willing to pay and how much a consumer actually does pay.
$12.00 + $15.00 + $23.00 = $50.00 (How much the consumer actually pays)
$23.00 + $26.00 + $30.00 = $79.00 (How much the consumer is willing to pay)
$79.00 - $50.00 = $29.00 (Consumer surplus)
