Annual oil production for a region was about 520 million tons n 1950. Production increased at a rate of 7.6% per year between 1950 and 1973, but the rate of growth then slowed. The oil production reached approximately 4 1 billion tons per year in 2016. Complete parts (a) through (d) below a Using the growth rate of 7 6% for the period 1950 to 1973 approximately what was the oil production in 1973? The oil production is approximately 2.8 illion tons in 1973 Round to one decimal place as needed.) b Starting from the result of part a approximately how much oil would have been produced in 2016 if growth n production had continued at a rate of 76% between 1973 and 2016 Compare this result to the actual 2016 figure given above The oil production is approximately 65.3 billion tons in 2016 Round to one decimal place as needed) The actual figure is far less than the figure calculated using 76% growth rate. c. Starting om he result of part a appro mately how much would have been produced in 2016 ifgro in oduction had proceeded at a rate of 2 % between 1973 and 15 Compare his result to the actual 2015 e given above The oil production is approximatelyillion tons in 2016 Round to one decimal place as needed.)
