Answer:
2.5
Step-by-step explanation:
The dilation is 2.5. Using the point b(0,4) and B' (0,10), divide 10/4 you get 2.5.
The width is 16 so the length is 64 (TO clarify W=16)

He was traveling 63 mph
divide 315 by 5 and you get 63
check your answer by multiplying his speed (63mph) by 5 (number of hours)
So you have to decrease £30 by 20%
To do this, an easy way would be to first take away 100% from 20% because you are DECREASING :
100 - 20 = 80
Then divide your answer by 100 :
80 / 100 = 0.8
This means 0.8 is going to be your multiplier so you do
0.8 * 30 = 24
Answer = £24
