Given the following information, determine the equation for the unit formulation. (Round intermediate calculations to 4 decimal places.

[Table Description: Table listing Unit Number (X) and Unit Cost ($Y). Unit 1 = $785.00 Unit 2 = $606.00, Unit 3=$519.50, Unit 4=$466.27]

Unit Number (X) Unit Cost (Y) $

1 785.00

2 605.00

3 519.50

4 466.27

Y = (785)(X) ^0.7100

Y= (785)(X) ^-0.4941

Y= (785)(X)^0.7707

Y= (785)(X)^-0.3758
