Question

describe the approximate tax T in dollars per ton that would result in p% (in decimal form) reduction in carbon  dioxide emissions. What tax will rediuse emission 75%

T=-0.65-193In(1-p)

Answer 1

What tax (T) will reduce emissions (p) by 75%?  The formula given for the Tax in the problem statement is:

 

T = -0.65 - 198*ln(1-p)

 

We want p = 75% = 0.75 (in decimal form).

 

T = -0.65 - 193*ln(1-0.75)

 

T = -0.65 - 193*ln(0.25)

 

Use your calculator to find the value of ln(0.25) and then complete the calculations to find T.  The units of T are dollars per ton.
