15-1/6n=1/6n-1
15+1=1/6n+1/6n
16=1+1/6n
16=2/6n
16=1/3n
16*3/1=n
therefore, n=48.........

Hey there!
The answer is $50 because $20 is 40%, so times that by 2 which you get $20 and 80%. Then you divide 20 by 2 then you get 10 which is 20% so you add 10 and you get $50 which is 100%
Hello there! When it comes to scientific notation, a number greater than or equal to 1, but less than 10 is multiplied by a power of 10. For example: 3.45 * 10^6. 0.95 is less than 1, so the first one is not in scientific notation. All of the others fit, because the numbers are greater than 1, but less than 10, and are mutliplied by a power of 10. The answer is A.
