9. Coal from source A produces sulfur at a rate of 18g per 100kg of coal. Coal from source B produces sulfur at a rate of 458 per 270kg of coal. Source A sells coal for $0.65/kg and source
B sells for $1.50/kg.
a. How many grams of sulfur would be released from the combustion of $100 of each
source of coal? (round to the nearest tenth)
b. We use about 7 billion metric tons of coal worldwide per year for electricity generation.
Using the least pollution coal source, how many kilograms of sulfur would be released
per year?
