All that you need to do is plug the value for x, 75, into the equation provided.
C=6350/(425-3x)
C=6350/(425-3*75)
C=6350/(425-225)
C=6350/200
C=31.75
C is the cost in millions, so we have to multiply our value of C by a million to get the total cost.
31.75*1000000=31,750,000
So, it costs $31,750,000.
