Write the formula for finding rate of discount after discount amount and marked price are given.
Answer:
Discount % = (Discount/List Price) × 100
Step-by-step explanation:
To calculate the discount, you must have the list price (marked price) and the selling price of the product you are buying.
Example: If the list price of a book is $50, and $10 discount is offered on the book, then the discount percentage is calculated as follows.
Discount % = (Discount/List Price) × 100
List price = $50; discount = $10
Discount (%) = (10/50) × 100
= 100/5
= 20%

x/7 = -57
Simplify your answer as much as possible
50 points to who answer's
[tex] \frac{x}{7} = - 57 \\ x = - 57 \times 7 \\ x = - 399[/tex]
The answer is -399.
[tex]\sf \longmapsto \dfrac{1}{7} x = - 57[/tex]
Multiply both sides by 7[tex]\sf \longmapsto7* (\dfrac{1}{7} x)=(7)*(−57)[/tex]

0.8x − 11 = 0.3x + 41
Answer:
0.8x − 11 = 0.3x + 41
0.8x-0.3x=41+11
0.5x=52
x=52/0.5
x=104
Answer:
x = 104
Step-by-step explanation:
0.8x - 11 = 0.3x + 41
0.8x - 0.3x = 41 + 11 (collecting the variables on one side)
0.5x = 52
x = 52 / 0.5
x = 104

Write an INEQUALITY that represents the sentence
1) The sum of a number and 5 is less than 7
2) The product of a number and 8 is at least 25
3) Six less than a number is greater than 54
4) the quotient of a number and 12 is no more than 6
Answer:
Step-by-step explanation:
Let n represent the unknown number.
1) The sum of a number and 5 is less than 7 becomes n + 5 < 7
2) The product of a number and 8 is at least 25 becomes 8n ≥ 25
3) Six less than a number is greater than 54 becomes n - 6 > 54
4) the quotient of a number and 12 is no more than 6 becomes n/12 ≤ 6
