The Fibonacci sequence is a simple yet extraordinary addition sequence.
1,1,2,3,5,8,13,21,34,55,89,144 and so on
By adding the previous two terms in the sequence, you can find out the next term. For example, 1+1=2, 1+2=3, 2+3=5, 3+5=8 and so on.
The seventh number is 13 and the ninth is 34.
Answer:
Option C: $30 is the original price of book.
Step-by-step explanation:
Let the original price of book be x
Given that:
Sale price = x - 40% of x
As it is given that the sale price was $18
So,
$18 = x - 40% of x
By simplifying:
$18 = x - 0.4x
$18 = 0.6x
Dividing both sides by 0.6:
x = $18/0.6
x = $ 30
So the original price of book will be $30

Answer:
Step-by-step explanation:
To calculate this you would first bring -14 over. In order to bring it over you would need to change the symbol from a minus to a plus, this cancels it out on the left but brings it over on the right. Then you are left with so you would divide it by 4 to find what e is equal to.
1) Bring the -14 over to the right.
Because we changed the symbol this cancels it out.
2) Then you would divide 24 by 4 to find out the answer for e.
