</span>Leah found that 25% of the students in her class
prefer ice cream for dessert
=> Now, if she has 24 students in her class. Let’s find out how many of her
students prefer ice cream for dessert.
=> 24 students = is the 100% of the number of student.
Now, 25% of it preferred ice cream as dessert. Lets solve
=> 25% / 100% = .25
Now, multiply this decimal with the value of our 100%
=> 24 * .25
=> 6, thus 6 of her students prefer ice cream for dessert.</span>
Answer:
13%
Step-by-step explanation:
<u>Given:</u>
- MP = 2080
- Discount = d%
- VAT = (d-2)%
- Cost = 1997.84
<u>Apply discount:</u>
- 2080 - d% = 2080*(1 - 0.01d)
<u>Add VAT:</u>
- 2080*(1 - 0.01d) + (d - 2)%
- 2080*(1 - 0.01d) * (1 + (d -2)/100)
- 2080*(1 - 0.01d) * (0.98 + 0.01d) = 1997.84
- (1 - 0.01d)(0.98 + 0.01d) = 1997.84/2080
- 0.98 + 0.01d - 0.0098d - 0.0001d² = 0.9605
- - 0.0001d² + 0.0002d + 0.98- 0.9605 = 0
- 0.0001d²- 0.0002d - 0.0195 = 0
- d² - 2d + 195 = 0
<u>Solving the quadratic equation we get:</u>
<u>Then</u>
Answer:
For your first answer it is because they are two different ways to solve the equation
Step-by-step explanation:
For Example!
<h2>Solution 1:</h2>
(x-4)² – 28 = 8
The 8 is positive making it a different equation (this is like absolute value). (I am assuming you know the answer to the probelm)
<h2>Solution 2:</h2>
(x-4)² – 28 = -8
The 8 could be negative meaning that when you add the 28 to the right side it is -8+28 which will be a negative!
