Ok so to solve for percent off
percent off means discount
so therefor we need to find how much was discounted
30-20.10=9.90
so we see that 9.90 was discounted
to find the percent we do
discount/total=percent discount
9.90/30=0.33
percent means parts out of 100
0.33/1 times 100/100=33/100=33%
answer is 33% discout

Answer:
6,700,000,000
Step-by-step explanation:
Standard Notation is the normal way of writing numbers.
Scientific notation of 6.7 * 10^9 would mean we need to move the decimal point "9" units "to the right" and arrive at our normal standard form of the number.
So, we move 1 decimal place and create 67. Then with the next 8 moves (to the right), we add 8 more zeros, so the number actually becomes:
6,700,000,000
This is 6 billion, 700 million.
This is the normal standard way (standard notation) of writing numbers.
