babunello [35]

The Benz C300 markup should be $15525. The markup price for the new Toyota Highland should be $43470

Step-by-step explanation:

For the used Benz C300

Initial price $12,000

Apply import duty for Nigeria which is 25%, which is similar to increasing the price by 25%

100% +25%=125%

12000*125/100 = $15000

Apply the 15% profit

100%+15%=115%

15000*115/100 =$17250

Apply the 10% discount, reducing the price by 10%

100%-10%=90%

17250*90/100 =$15525

The Benz C300 markup should be $15525

For the Toyota Highlander

Initial price = $30,000

Apply import duty for Nigeria for new cars, which is 40%, which is similar to increasing the car price by 40%

100%+40%=140%

30,000*140/100 =$42000

Apply the 15% profit

15%+100%=115%

115/100*42000 =$48300

Apply the 10% discount

100%-10%=90%

48300*90/100=$43470

The markup price for the new Toyota Highland should be $43470

1. Annual percent increase in rent is basically just a percentage of the rent increased each year.

2. Heater: Use fire places, or lower the amount of air conditioning usage so it's not so cold.

Electricity: Turn off ceiling fans and lights when not used, or only allow the essential things to use electricity.

Water: Not leave faucets or showers running, or no bathtubs which prevents baths.

3. The couple could save $450 in one year because 3000 divided by 0.15 which is the 15%, equals to the total amount saved at $450.

4. Groceries/everyday essentials, Gas money, taxes, pay off loans.

Giving the following information:

items:

fruit juice. $0.89

iced tea. $1.29

lemonade. $1.49

pretzel. $2.50

popcorn. $1.25​

First, popcorn and pretzel are not beverages.

<u>Now, we need to find the differences in prices between each beverage and determine the greatest:</u>

Fruit juice to ice tea= 0.89 - $0.4

Fruit juice to lemonade= 0.89 - 1.49= $0.6

Ice tea to lemonade= 1.29 - 1.49= $0.2

PLEASE HELP I WILL MARK BEAINLIST
Vlada [557]

Answer:

5981.25 m²

Step-by-step explanation:

1. Divide the court into two sections. One section being the semicircle, the other being the rectangle.

2. Multiply 100 by 50 to get the area of the rectangle, which is 5000.

3. Divide 50 by 2 to get the radius of the semicircle, which is 25.

4. Find the formula used for area of a semicircle A = \frac{1}{2}\pir²

5. Insert 25 into where the "r" is in the equation: A = \frac{1}{2}\pi(25²), resulting in about 981.25. (I replaced \pi with 3.14)

6. Add the area of the rectangle with the area of the semicircle, 5000 + 981.25 = 5981.25.

7. The final answer is 5981.25 m².
