Answer:
$5282.70
Step-by-step explanation:
the formula for calculating future value when there is continuous compounding is : A x e^r x N
A= amount e = 2.7182818
N = number of years
r = interest rate
2500x e^0.055 x 2 = 5282.70
Hello!
x² + 6x + 1 = x - 3
Bring all terms to one side by subtracting x and adding 3:
x² + 6x - x + 1 + 3 = x - x - 3 + 3
x² + 5x + 4 = 0
Factor:
(x + 4)(x + 1) = 0
Set each factor to 0:
x + 4 = 0
x = -4
x + 1 = 0
x = -1
Answer:
68
Step-by-step explanation:
Alright, so to find how many pages that can be had, we have to replace P with the amount of money Jennifer has. This is because P is the price of one book, and we want to find the number of pages (x) we can buy for a book price of 62.10 or less.
62.1 = (20 + 0.5x) + 0.15(20 + 0.5x)
62.1 = 20 + 3 + 0.5x + 0.075x
62.1 - 23 = 0.575x
39.1 = 0.575x
39.1/0.575 = x
x = 68
Therefore, in order to buy a book that costs 62.10, the book must have 68 pages.
