Answer:
Distance from Earth to Proxima Centauri (in scientific notation) = kilometers
Step-by-step explanation:
We need the conversion between Astronomical Unit and Kilometers.
The conversion is:
1 AU = 1.496*10^8 km
or rounded, given in this problem,
1 AU = km
We need the distance from Earth to Proxima Centauri:
AU * kilometers
When multiplying two numbers in scientific notation, we have to "multiply the coefficients" and "add the exponents".
Lets do this:
Distance from Earth to Proxima Centauri (in scientific notation) = kilometers
0.52944444444 you can simplify the decimal and you will have the answer

Answer: £5000
Step-by-step explanation:
If 12% decrease = £600
Then (100- 12)% = x
100% = x
0.12x = 600 x 0.88
0.12x = 528
Divide both sides by 0.12
£4400
Therefore, original price before 12% decrease was £5000
