Original Price:
Decrease by 85%
Final Price $12.99

Solve for the original price.

Answer:

$86.60

Step-by-step explanation:

Method 1: 12.99 ÷ 15 × 100 = 86.6

Method 2: 12.99 ÷ 15% = 86.6

Using (15 × 100) or 15% because 100% - 85% = 15%

A large bag contains 16 red, 48 blue, and 16 green marbles. Each student in Mrs. Wynn's class randomly selects a marble, records the color, and then puts the marble back into the bag. Mrs. Wynn then reports the total number of red, blue, and green marbles selected by the entire class. Which of these statements are true? Choose all that are correct. A. Theoretically, the probability of selecting one red marble from this bag is 0.20. B. If the total number of red marbles selected is not equal to the total number of green marbles selected, then there was a mistake in selecting the marbles or recording the data. C. If there are 30 students in the class, the total number of blue marbles selected should be about 18 but may be more or less. D. If a student does not return his or her marble to the bag before the next student selects his or her marble, the theoretical probability of selecting a blue marble may be different for the next student. E. It is possible that every student selects a green marble.

1. The prism-shaped roof has equilateral triangular bases. Create an equation that models the height of one of the roof's triangular bases in terms of its sides. In your final answer, include all necessary calculations.
2. The prism-shaped roof has equilateral triangular bases. Use the model you created in question #1 to calculate the height of the roof, to the nearest tenth of a foot, if the side lengths each measure 25 feet. In your final answer, include all necessary calculations.

3. To determine the amount of roofing materials needed, the area of the roof's entire surface is calculated, including the ceiling of the garage. Considering the sketch of the roofing design, create a formula to model the area of the roof's entire surface. In your final answer, include all of your calculations.

4. The contractor in charge of the roofing project is trying to make the job the most cost effective for the homeowners. In order to cut back on the cost of supplies, he decides that a ceiling in the garage is not necessary. In other words, there will not be a barrier built between the garage and the roof. In two or more complete sentences, explain how these changes affect the model for the area of the roof's entire surface.
