Answer:
Thomas observed a physical change
Step-by-step explanation:
Water does NOT change chemically when it turns into ice.
It changes forms of liquid to solid, temporarily, and can be easily made back into liquid form by melting.
Nothing was created nor destroyed.
Therefore, it is a physical change because the physical properties of the water changed, not its H2O element.
Let the original price be 'x'
7/100 * x + x = 305
(7x+100x)/100 = 305
107x = 305 * 100
107x= 30500
x= 30500/107
x= 285.04
Therefore, the original buying price is £ 285.04

Answer:I need to see the graph to answer your question
20%
to find out we make it a fraction:
14/70
then divide
14÷70=0.2
then times it by 100
= 20%
Can you post what it says? I could probably help you out.
