where A=final amount
P=principal
r=rate in decimal form
t=time in years
we are given that P=500, r=12%=0.12
we want to find A when t=10, 20, and 30
so


when t=10, 
when t=20, 
when t=30, 
Answer: a. 320 books
Step-by-step explanation:
Given : The total number of books were placed on the discount shelf for 70% off the regular price = 960
The fraction of books sold = 
Then, the number of books sold = 
Now, the number of books remain on the discount shelf = 
Hence, the number of books remain on the discount shelf =320
Answer:
The coordinates of point X are (-11/2, 5/2)
Step-by-step explanation:
To find the coordinates of X , we shall apply the midpoint formula;
Mathematically, that would be;
(x , y) = (x1 + x2)/2 , (y1 + y2)/2
From the question
x1 = -3 , x2 = -8
y1 = 1 , y2 = 4
So substituting these values, we have;
(x ,y) = (-3-8)/2, (1 + 4)/2
(x ,y) = -11/2, 5/2
Answer:
It would be D because you are timing 2 by a number which would have n together
Hope this helped
Answer:
<h2>
y = 3.5x + 15</h2>
Step-by-step explanation:
Number of months is x, and number of pairs of shoes after each month is y.
7 new pairs of shoes every 2 months means that after each month:
y = 7/2 x
We need to add the 15 pairs from start.
y = 3.5x + 15
