2 and 1/2 because 2 shots would be 50% and 3 would be 75% so it would have to be 2 and 1/2 shots.
1. 6 feet long
2. The border increases the length of each side by 1 foot
3. The width of the border is 6 inches (0.5 feet) because it adds on 1 foot in length to each side. Splitting it between the 2 borders for each side would make it 6 inches.

There are 12 months in a year. He plans on visiting 8 times each month.
Step One
Find the number of visits per year.
<em>Givens</em>
Number of visits per month = 8
Number of months per year = 12
Visits = # visits / month * number of months
Visitis = 8 * 12
Visits = 96 visits in total.
Step Two
<em>Calculate the cost / visit</em>
Total Cost = 414 visits.
Total Visits = 96
Cost / Visit = Total Cost / Total visits.
Cost / Visit = 414 / 96
Cost / Visit = 4.31 roughly.
You can solve this problem in multiple ways, but you'll have to divide the total volume with the amount per servings to find the number of servings (makes sense logically if you think about it).
The first way is to just use the fractions given. This will usually be your method in handling this if you're not familiar with it.
Convert 6 3/4 into an improper fraction. To do this, we need to put the 6 into the numerator somehow. We can approach this by multiplying the whole number (6) with the denominator (4) and adding it to (3). Basically, 6 x 4 + 3 = 27. This will be our new numerator. If you are not familiar with this concept, please let me know.
Our new fraction for the total amount of juice is
. Divide this with the amount per serving,
We flip the second fraction over and multiply it.
(I crossed out common numbers here, unfortunately I don't know how to do that here so let me know if my explanation was not clear enough. I skipped a few steps.)
18 servings would be your answer.
Or you can convert 6 3/4 into decimal, which would be 6.75. 3/8 in decimal is .375 and you can do long division from there. That way is a bit more tedious in my opinion, but sometimes more convenient.
Cheers!
Option A
The simple interest earned is $ 105
<em><u>Solution:</u></em>
Given that, $300 at 5% annual interest for 7 years
Therefore,
Principal = $ 300
Rate of interest = 5 %
Number of years = 7
<em><u>The simple interest is given by formula:</u></em>
Where,
p is the principal
r is the rate of interest
n is the number of years
<em><u>Substituting the values in formula,</u></em>
Thus simple interest earned is $ 105
