The correct statement is that at the end of two years a total interest of 1246.10 has been paid on a principal of $11940, where the interest rate is 7.45 percent. So, the correct option is B.
The calculation on monthly payment of interest can be done by ascertainment of the interest paid for two years and division of such amount by total number of months.
<h3>Calculation of Monthly Payment</h3>
We know that the interest to be paid for the first year will be close to $902 and that for the second year will be calculated as follows,

So, the total interest paid at the end of the second year will be,

So, the total interest paid fully at the end of two years will be $1246.10
Hence, the correct option is B that the total interest of 1246.10 has been paid on a principal of $11940 at the end of two years upon monthly payments of such years.

Answer:
Explanation:
a) x1 = number of unit product 1 to produce , and
x2 number of unit product 2 to produce
A linear program that will maximize world light profit is the following
maximize
subject to 

Unit 1 is used both in products in 1 : 3 ratio which can be a maximum of 200 unit 2 is used in 2 : 2 ratio which can be maximum of 300
So, this can be written as the inequations
Profit functio is p = 0ne dollar on product A and two dollar on product B
= x + 2y
Now , we find a feasible area whose extremeties will give the maximum profit for, the graph is ( see attached file )
So on the graph, we can get the other extremeties of the shaded regional so which will not give maximum profit ,
Thus , the maximum possible profit is
p = ($1 * 125) + ($2 * 25)
= $175
Answer: 21%
Explanation: The developer purchased 3 properties and he can buy each property for $20 per square foot.
Therefore: 75 × 110 =8250 square feet.
8250 × $20 = $165 000 per lot.
Each lot was sold for $200 000. Which means the developer made profits of:
$200 000 - $165 000 = $35 000 per lot.
The percentage of profit on each lot is:
Percentage of profit on cost amount:
= 
= 0.2121212 recurring × 100
= 21,21%
Percentage of profit on sale amount:
= 
= 0.175 × 100
= 17,5%
