The value of a book is $150 and decreases at a rate of 4% per year. Find the value of the book after 12 years
Answers
100% - 4% = 96% = 96/100 = 0.96
At the end of the 1 year its value becomes: 150*(0.96)
At the end of the 2 years its value becomes: 150*(0.96)*(0.96) = 150*(0.96)²
At the end of the 3 years its value becomes: 150*(0.96)*(0.96)*(0.96) = 150(0.96)³
So similarly at the end of 12 years, its value becomes 150*(0.96)¹²
=50*(0.96)¹² simplify with calculator.
≈ 91.91
Value at the end of 12 years becomes ≈ $91.91
I hope this helps.

The distance between the first and last plant is .
Further explanation:
Given:
A farmer is planting a straight row of crops with 3 feet between each plant.
Calculation:
Consider the number of plant as .
The number of spaces between the plants is calculated as follows:
……(1).
Since, the number of plants are 23, Substitute 23 for in equation (1) to obtain the number of spaces between the plants.
Since, the distance between each plant is 3 feet, the distance between the first and last plant is calculated as follows:
……(2)
Substitute 22 for in equation (2) to obtain distance
between the first and last plant.
Thus, the distance between the first and last plant is .

Final answer:
The distance between the first and last plant in a straight row of 23 crops with a spacing of 3 feet each is 66 feet. This is calculated using the formula: (Number of plants - 1) * Distance between plants.
Explanation:
The problem requires you to find the total distance from the first to the last plant in a row of crops considering that each plant is planted 3 feet apart. This type of problem can be solved by simple arithmetic calculations.
You might think you should simply multiply the number of plants by the distance between them, but this would not provide the correct answer. The reason is that the distance between the plants is not the same as the distance from the first to last plant.
For example, if the farmer only planted two crops, there would only be 3 feet between them, not 6. Therefore, we need to use the formula: (Number of plants - 1) * Distance between plants.
To solve for our question, we’d get: (23 plants - 1) * 3 feet = 66 feet. Thus, the distance between the first and last plant is 66 feet.

cost = 7.45
selling price = 9.95
9.95 - 7.45 = 2.50 mark up
2.50 / 7.45 = 0.3355
0.3355 * 100% = 33.55% or 33.6% is the percentage of mark up to the nearest tenth.
That represents (2.5/7.45) *100% = 33,6%.
b. The number is not divisible by 5.
c. The number is even or less than 12.
d. The number is neither prime nor composite.
e. The square root of the number is less than 3.
Answers
a) 2 is part of the set and 2 is not greater than 2. NO
b) 5 and 10 in the set are divisible by 5. NO
c) 2,4,6,8,10 are even but the rest are odd ( BUT note the word "or"). the rest are less than 12. YES
d) 0 and 1 are the only numbers that are neither prime nor composite (they're not even part of the set). NO
e) the square root of 9 is 3 so the maximum number is 9 (but what happened to 10?) NO
For our given sample, the only true statement is:
c. The number is even or less than 12.
Which event, covers the entire sample space of this experiment?
The sample for the experiment is the set:
{2, 3, 4, 5, 6, 7, 8, 9, 10}
So, we need to see which ones of the statements are true for every digit in that set.
For example:
a "The number is greater than 2."
Is false, because the outcome can be 2, as 2 belongs to the set.
The true statement is:
c. The number is even or less than 12. (all the numbers are less than 12).
