The second worst oil spill was in 1991 off Angola. 1. The spills together released 547 thousand tons of oil. The worst spill released 27 thousand tons more than the second worst spill. How many tons of oil did the worst spill release? Show or explain all of your work. 2. Between 1990 and 1999 there were 58 oil spills that each released more than 7 tons of oil totaling 118 thousand tons. Seventy-three percent of the oil spilled occurred in 10 incidents. To the nearest tenth of a percent, what percent of the oil spills did the 10 incidents represent? Show or explain all of your work.. The total amount of oil spilled in the 1990s was 1 the amount spilled in the 1970s and 8 thousand tons less than the oil spills of the 1980s. Using one variable, write an expression that represents the oil spills for each decade. 4. The total amount of oil spilled during the past decades was approximately 5278 thousand tons. Using the expressions from Part, what was the total quantity of oil spilled each decade? Show or explain all of your work. BE SURE TO LABEL YOUR ANSWERS 1, 2,, AND 4. 4

7 Solution and Scoring Scoring: Part 1: Part 2: Part : (2 points possible) Score 1 point for the correct answer of 287 thousand tons. AND Score 1 point for correct and complete procedure shown and/or explained. OR Score ½ point for correct procedure with calculation or copy error in work shown. (1 point possible) Score ½ point for correct answer rounded to the nearest tenth of a percent. AND Score ½ point for correct and complete procedure shown and/or explanation given. (Rounding is not an issue for this ½ point.) (1½ points possible) Score ½ point for each expression. Part 4: (Based on student's answer in Part.) (2 ½ points possible) Score ½ point for each correct decade value. AND Score 1 point for correct and complete procedure shown and/or explanation given. Solution: Part 1: (x + 27) + x = 547 2x + 27 = 547 x = = 287 thousand tons Part 2: Part : = % 90s = 1 x 80s = 1 x s = x Part 4: 1 x + 1 x x = x + 8 = x = 5240 x = s = 144 thousand tons 1980s = 1 (144) + 8 = 1086 thousand tons 1990s = 1 (144) = 1048 thousand tons
