Two !!!! ... unless this is some riddle and there's a huge in depth meaningful answer i'm unaware about o.O
<h3>Answer: 7366.96 dollars</h3>
========================================================
Use the compound interest formula:
A = P(1+r/n)^(n*t)
where in this case,
A = 12000 = amount after t years
P = unknown = deposited amount we want to solve for
r = 0.05 = the decimal form of 5% interest
n = 1 = refers to the compounding frequency (annual)
t = 10 = number of years
-------
Plug all these values into the equation, then solve for P
A = P(1+r/n)^(n*t)
12000 = P(1+0.05/1)^(1*10)
12000 = P(1.05)^(10)
12000 = P(1.62889462677744)
12000 = 1.62889462677744P
1.62889462677744P = 12000
P = 12000/1.62889462677744
P = 7366.95904248911
P = 7366.96
we are given two points as
(3, 16) and (5, 10)
firstly , we will find slope
slope is m
so, we can use formula
now, we can plug points
we can plug it in y=mx+b
we get
now, we can select any one points
and find b
(3,16)
x=3 and y=16
we can find b
now, we can plug back b
and we get
so, equation is
and
...............Answer
We can do this by just adding 14 to 14 until we get a number that is divisible by 10. We can do it this way because it will be a small number. Let's list them out. 14, 28, 42, 56, 70. 70 is divisible by 10, so 70 is the answer.
