Answer:
The answer is "$10.12 million"
Explanation:
To find the price of the 36 dock doors only at the current rate, just use the cost index.
[tex]C_n=C_k \times (\frac{I_n}{I_k})\\\\[/tex]
[tex]= 6 \times \frac{195}{140} \\\\= \$ \ 8 \ million[/tex]
Its current cost of 36 dock doors is, thus,[tex]\$ \ 8 \ million[/tex]. To calculate the price for 48 dock doors, just use the second formula now:
[tex]\to (\frac{C_A}{C_B})=(\frac{S_A}{S_B})^{X}\\\\\to C_A=C_B \times (\frac{S_A}{S_B})^{X}\\\\[/tex]
[tex]=8 \times (\frac{48}{36})^{0.82}\\\\= \$ 10.12 \ million[/tex]
