Answer:
<h2>BR ≈ 49.0</h2>
Step-by-step explanation:
Use cosine:

We have


Substitute:

<em>cross multiply</em>
<em>divide both sides by 8,572</em>


Important variables to know:
I = interest
P = principal (investment)
R = simple interest rate
T = years
Formula: I = PRT
What information do we have?
I = $960
P = $4000
T = 3 years
R = ?
Plug into formula:
960 = 4000(3)(R)
960 = 12000R
R = 960/12000
R = .08
A. $4000 + $960 = $4960. (A= P+ I)
B. 8% (.08)
Part 2: 1080 = 4000*.09*3
A = 5080 - 4960 =$420.
836 to the nearest hundred is 800 because number under 50 of the last two digits we round it below. Same thing as above 50 we round it up.
