Week three Term 2 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? //I used 100 liters as my example. 30% of 100 is 30 litres that leaves me with 70 litres and 40% OF 70 LITRES IS 28 litres in total there is a saving of 58litres per 100 litres of fuel.// **======

**__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?

**50% percenet of the students play golf and tennis because 80% + 70% = 150 so you cut down the 80 and 70 by thirty and twenty and that leaves 50.**
Extension: What is the smallest number of students in that class?
