1-1 (a) 62 million tons per year × (0.05) = 3.1 million tons per year of reduced greenhouse gas
$1.2 billion ÷ 3.1 million tons per year = $387.10 per ton
(b) 3 billion tons per year × (0.03) = 90 million tons per year of reduced greenhouse gas
$1.2 billion $X billion
=
3.1 million tons 90 million tons
X = $34.84 billion
