Answer:

Step-by-step explanation:
If the unit selling price is 2.50 and the unit cost is 1.00 what action is needed to maintain the gross margin percentage when unit cost increase 0.25
The original gross margin is (2.50 / 1.00) - 1 = (2.5 - 1) = 1.5 = 150%
the cost increases 0.25, is an increase of (0.25 / 1.00) = 25%
in order to keep the same gross margin, you need to increase the sale price by 25%
2.50*1.25 = 3.125
Then the gross margin is (3.125 / 1.25) - 1 = (2.5 - 1) = 1.5 = 150% ( same as original )

In the 1980s, the population of Pleasanton decreased by 10%. In the 1990s, its population increased by 30%.
How does the population of Pleasanton at the end of the 1990s compare with its population in 1980?
A) It is 20% higher. B) It is 23% higher. C) It is 40% higher. D) It is 17% higher.
The population of Pleasanton is 17 % higher. (Right choice: D)
According to the statement, the population of Pleasanton is reduced by a factor of 0.9 in the 1980s and increased by a factor of 1.3 in the 1990s. The increase rate is found by means of this formula:
[tex]x =[(0.9)\cdot (1.3)-1]\cdot 100[/tex]
[tex]x = 17\,\%[/tex]
The population of Pleasanton is 17 % higher. (Right choice: D)
To learn about percentages, we kindly invite to check this verified question: https://brainly.com/question/834969
The population of Pleasanton at the end of the 1990s is 17% higher than the population in 1980.
Explanation:To compare the population of Pleasanton in the 1990s with the population in 1980, we need to consider the changes that occurred in each decade. In the 1980s, the population decreased by 10%. This means that if the population in 1980 was represented by 100, it would have decreased to 90 by the end of the decade.
In the 1990s, the population increased by 30%. Using the population of 90 at the beginning of the decade, the population at the end of the 1990s would be 90 + (30% of 90) = 90 + 27 = 117.
So, the population of Pleasanton at the end of the 1990s is 117, which is 17% higher than the population in 1980. Therefore, the correct answer is D) It is 17% higher.

Short Cut That My Teacher Taught Me :)
0.1 repeating has 1 digit repeating after the decimal point, so there is one digit in the denominator. Put the repeating digit in the numerator place. That's your answer. You can do the same to any repeating decimal: 2 digits after the point has 99 as the denominator, 3 digits is the repeating number over 99, and so on.
Apartment A has a security deposit of $1000 and cost $1200 each month. Apartment B has a $1500 security deposit and cost $1175 each month. How many months will it take for the costs to be the same?
It will take 20 months for the costs of Apartment A and Apartment B to be the same.
Explanation:To find out how many months it will take for the costs of Apartment A and Apartment B to be the same, we need to set up an equation. Let's say it takes x months for the costs to be equal. The equation would be: 1000 + 1200x = 1500 + 1175x. We can solve this equation to find the value of x.
First, we can simplify the equation by subtracting 1175x from both sides: 1000 + 25x = 1500. Then, we can subtract 1000 from both sides to isolate the variable: 25x = 500.
Finally, we can divide both sides of the equation by 25 to solve for x: x = 20. Therefore, it will take 20 months for the costs of Apartment A and Apartment B to be the same.
