The effective annual interest rate calculations yield:
i = (1 + 0.064/12)^12 - 1 = 0.066
For year 1: the interest amounts to $613.80 (calculating $9300 multiplied by 0.066)
For year 2: the interest totals $654.31 (adding year 1’s interest to $9300 and multiplying by 0.066)
For year 3: the interest is $656.98 (following the same process as year 2)
For year 4: the interest is $657.16

The cumulative interest totals: $2582.25
The present value of this sum is:
P = 2582.23 / (1 + 0.066)^4 = $1999.72

Thus, the final answer is $1999.72.

Answer: The loss percentage per gallon is 23.17%

Step-by-step explanation:Original price per gallon is $ 2.59

Discounted price per gallon is $ 1.99

Now, we will calculate the percentage loss per gallon, using the Direct Rule of Three as follows:

Price      Percentage

2.59           100

1.99               x*****************************

2.59 * x = 1.99 * 100

2.59x = 199

x = 199/2.59

x = 76.83

So the percentage loss = 100 - 76.83

The percentage loss is 23.17%
