Answer:
The total amount due after five years is $57,000.
Step-by-step explanation:
Recall that simple interest is given by the formula:

Where <em>A</em> is the final amount, <em>P</em> is the principal amount, <em>r</em> is the rate, and <em>t</em> is the time (in years).
Since we are investing a principal amount of $38,000 at a rate of 10.0% for five years, <em>P</em> = 38000, <em>r</em> = 0.1, and <em>t</em> = 5. Substitute:

Evaluate. Hence:

The total amount due after five years is $57,000.
Answer:
$720
$360
Step-by-step explanation:
Let the cost of couch be A and that of coffee table be B
Given couch and coffee table cost $1080
That’s
A + B = $1080
Also, the cost of couch A is 2 times the cost of coffeee table B.
That’s
A = 2B
We now have two equations
A + B = 1080
A = 2B
Now ,substitute 2B for A in the first equation .
We have
A + B = 1080
2B + B = 1080
3B = 1080
Divide both sides by 3
3B/3 = 1080/3
B = 360
The coffee table cost $360
Remember A = 2B
Therefore
A = 2 x $360
A = $720
The couch cost $720 while the coffee table cost $360
Answer:
(4,7) and (0,1)
Step-by-step explanation:
(7-4)/(4-2) = 3/ 2, and (4-1)/(2-0) = 3/2.
Doing (7x÷7) I think equals 1
Answer:
3yrs
Step-by-step explanation:
Given parameters:
Capital = $700
Percentage interest = 4% per annum
Unknown:
Time it will take for amount to be = $784
Solution:
To find the simple interest on an amount;
I = 
P is the principal
R is the rate
T is the time
I is the interest
Insert the parameters:
I = 
I = 28T
So;
At the end of the duration:
Principal + Interest = Amount
700+28T = 784
28T = 784 - 700
28T = 84
T = 3yrs
