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%

1. The cost of 4 hates is $29.68. What is the unit price?
2. Jess types 625 words in 6 minutes. How many words can Jess type per minute?
To find the unit price, divide the total price by the number of items. A unit price is a unit rate for one item.
1. 29.68 / 4 = 7.42
So $7.42 is the unit price.
2. 625 / 6 = 104 (rounded to the nearest whole number)
So Jess can type 104 words per minute.
Answer:
1. 7.24
2. 104
Step-by-step explanation:
1. divide 29.68 by 4
> 29.68÷4
> 7.24
therefore the unit price is 7.24
check: 7.24x4=29.68
2. divide 625÷6
> 625÷6
> 104.1666667
> 104.1666667 round off 104
therefore he can type 104words per minute

Step-by-step explanation:
I hope this helps
Have a blessed day
The difference between the high temperature and the low temperature is 24.3 F.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the high temperature was recorded as 19.8°F. The low temperature that same day was recorded as −4.5°F.
The difference will be calculated as,
D = High temperature - low temperature
D = 19.8 - (-4.5)
D = 24.3 F
Therefore, the difference between the high temperature and the low temperature is 24.3 F.
