Answer:
£1920
Step-by-step explanation:
The amount she spent in 2016 is 20% less than 2017. 20% less than is the same as 80% of the amount she spent in 2017. So, to find how much she spent in 2016, multiply 2400 by 0.80 (the decimal form of 80%):
2400 * 0.8 = 1920
Emily spent £1920 on holiday in 2016.

Answer:
I think this is the answer
Area 77cm2
Here is how to solve it:
<span>Distance1 ÷ (plane velocity + wind velocity) = Distance2 ÷ (plane velocity - wind velocity)</span>800 / (180 + wv) = 640 / (180 - wv)
115,200 +640 wv = 144,000 - 800 wv
1,440 wv = 28,800
wind velocity = 20 mph
