Question: Kat gets a 95% on her first math test and an 80% on her second math test. If she wants an average grade of at least 90% in her math class, what does she need to get on her third final math test?
Answer: Let x = the percent needed on her third math test. (95 + 80 + x) / 3 = 90. (95 + 80 + x) = 270. x = 270 - 95 - 80. x = 95. The answer is 95.

Question: Bill is doing weight training before trying out for the boxing team. He gets two 2-gallon jugs and fills them 70% full with sand. If sand has a density of 5 pounds/gallon, how many pounds do Bill's improvised weights weigh?
Answer: First find the volume of the sand in one jug: 2 gallons * 70% = 1.4 gallons. Then double this amount since there are two jugs: 1.4 gallons * 2 = 2.8 gallons. Then multiply the total volume by the density of sand to find the total weight: 2.8 gallons * 5 pounds / gallon = 14 pounds. The answer is 14.
