Oakland is a growing industrial town. Every year, the level of CO2 emissions from the town increases by 10%. If the town produced 340,000 metric tons of CO2 this year, how much will be produced 7 years in the future?
Answer provided by our tutors
After 1 year there will be: 340,000 + 0.10*340,000 = (1 + 0.10)*340,000 metric tons of CO2
After 2 yeas there will be: (1 + 0.10)*340,000 + 0.10*(1 + 0.10)*340,000 = (1 + 0.10)^2*340,000 metric tons of CO2
........
After 7 yeas there will be: (1 + 0.10)^7*340,000 = 1.10^7*340,000 = 662,563.814 metric tons of CO2
