Answer:
The cost of extracting the first 50 tons of copper is $151,000.
Step-by-step explanation:
Start-up costs of $150,000.
For the 50 tons of cooper.
[tex]C(x) = 0.6 + 0.008x[/tex]
So
[tex]C(50) = 0.6 + 0.008*50 = 1[/tex]
1 thousand dollars.

$150,000 + $1,000 = $151,000
The cost of extracting the first 50 tons of copper is $151,000.
