We need to use the formula for simple interest which is
I= prt
Where I is the amount of money you earned or pay in interest
p is the principal, the amount you deposited or borrowed
r is the interest rate expressed as a decimal
t is time in terms of years
In this problem, I= 1,680
p= 3000
t= 8
'. r is what we are looking for.
Substituting the numbers into the simple interest formula, we get
I=. p r t
1,680=(3000)(r)(8). Multiplying
1,680= 24,000r Divide both sides by 24,000
0.07= r
So, the percentage is (0.07)(100)= 7%...
Answer:
c. In 2 seconds, the commuter train travels 120 feet.
Step-by-step explanation:
Given
The attached graph
Required
What does x-coordinate of 2 represents
Represent this coordinate with (x,y)
From the graph:
when 
Note that:
x = time and y = distance
So:

Which means:
At 2 seconds, the train has travelled a distance of 120ft
<em>From the list of options, (c) is correct</em>
Answer:
The equation to find profit would be y=5.25x-1,150
I'm not sure of what exactly you are looking for, If you need something else let me know and I'll be happy to help!
Step-by-step explanation:
Procedures can also be called methods because they are like steps and rules that you can follow.
If you crossed multiplied than got an equation than x=6 ( if that's what your looking for)
