Let's place a quartet on Race 7 AJ Scahill Stakes.

First Box:

ELLICORSAM, AVENIDA MADERO

Second Box:

ELLICORSAM, AVENIDA MADERO, ARTIC PARK

Third Box:

ELLICORSAM, AVENIDA MADERO, ARTIC PARK, STAR LASER

Fourth Box:

ELLICORSAM, AVENIDA MADERO, ARTIC PARK, STAR LASER, MONDANEY

That equals 16 combinations, so it should cost $16 I think.

Good Luck & Good Punting.
