The amount of money paid be Marine can be determined by multiplying the pounds of roast beef bought by its cost per pound.
i.e amount paid = number of pounds of roast beef bought x cost per pound

= $9.375
The amount paid = $9.38
Therefore, the total amount of money paid by Marine for 2.5 pounds of the roast beef is $9.38.
