Answer:
quarterly N = 4
semi-annually N = 2
Monthly N = 12
annually N = 1
Step-by-step explanation:
Given the following compound interest times :
N = number of times interest is compounded per period :
A period is regarded as a whole year.
Interest compounded;
QUARTERLY = Every 4 months per period = 12/3= 4
SEMI ANNUALLY = Every 6 months per period = 12/6 = 2
MONTHLY = Every month = 12 / 1 = 12
ANNUALLY = Every 12 months = 12 /12 = 1

Answer:
{1, -9, 56, -269}
Step-by-step explanation:
Evaluate the rule for n=2, 3, and 4 in sequence.
For n=2
f(2) = (-5)f(1) +11 = (-5)(4) +11 = -9
f(3) = (-5)f(2) +11 = (-5)(-9) +11 = 56
f(4) = (-5)f(3) +11 = (-5)(56) +11 = -269
The first four terms of the sequence are {1, -9, 56, -269}.
From the information we have, we know that each book costs 1.20 dollars. So we shall say this price is at 100% .
Now we need to form an equation to get the percentage when the books are sold at 0.80 dollars.
100% = 1.20
x = 0. 80
Where x is the new percentage when the sale is at 0.80 dollars.
We cross multiply the equation:
1.20 *x = 0.80 * 100
1.2x = 80
x = 80/1.2
x = 66.7%
Round off 66.7 to the nearest tenth we get 67%
The notebooks are sold at 67% (of the original cost).
