The original cost of a piece of equipment was $5,000 when the M&S equipment index value was 1105.2. If the index value is now 1520.3, estimate the cost of the tunnel twice as large. Assume the original quantity is 1 cubic foot in size. The cost-capacity equation exponent is 0.89. (Choose the closest answer) $11,185 $8,318 $10,532 0 $13,165
