__**Week One Term 2**__ Tennis & Golf In a class in the school down the road, everyone plays tennis or golf or both. In fact 80% play tennis and 70% play golf. What percentage plays both games?

If 80% play tennis 70% play golf then the remaining percentage out of each sport must play both. 20% of tennis plus 30% of golf equals 50% who play both. Extension: What is the smallest number of students in that class? =10 Because 7 play golf and 8 play tennis and 5 people play both.7+8=15-5=10

**__Fuel Savings__** NASA has been trying to reduce the fuel consumption of its large rockets. Two companies, MOREGAS and JeTSAVE have come up with separate devices to save fuel. The MOREGAS invention will save 30% of fuel and JeTSAVEs attachment will save 40%. One of the brains at NASA decides to couple the two devices. How much fuel can they save together? if the rocket needed 1000L to get to the moon and you connected the MOREGAS device then a 30% saving would mean that you would only need 700 litres to go the same distance. If you add on the JETSAVE device you can save 40% more off 700 litres because you have already saved 300 litres so 40% of 700 litres is 280 litres. When you add the two savings together it equals 580 litres.580 litres is 58%
