Answer: Hassan's expression:
d = original price
0.25d = amount of discount
d-0.75d= sale price of the book
Bella's expression
0.75d = sale price of a book
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
d = original price in dollars
25% off = 0.25 in decimal form ( 25/ 100 = 0.25)
Hasan's expression:
d−0.25d
In this expression 0.25d is the amount of discount , and d is the original price.
For example :
If a book costs $100 (original price) :
sale price =100 - (0.25 x 100)
sale price=100- 25
sale price=75
Bella's expression:
0.75d
in this expression 0.75d is the sale price ( d is the original price and since the percent discount is 0.25 it can be expressed as a 0.75 of the original price since 100-25=0.75)
Answer:
option D
2x4; -11
Step-by-step explanation:
Order of matrix is in form (m x n), here m is the row and n is the column of the matrix.
So this matrix have 2 rows and 4 columns
1)Order of matrix
2x4
2)
here 1 is the row and 2 is the column
-11
Each elements of the matrix can be identity as below

Answer:
f(x) = 0.5x + 5
Domain: positive whole numbers
Range: f(x) ≥ 5
Step-by-step explanation:
Let's x denote the total number of fruit juice.
This means that if $0.5 for each fruit juice, then the total cost incurred for fruit juice would be $0.5x.
Since she incurred a cost of $5 for 100 cups and $0.5 for each fruit juice, then the total cost, f(x), would be:
f(x) = 0.5x + 5
The domain would be all positive whole numbers (it is restricted to positive whole numbers because a fruit juice can't be "negative" neither can it be "half").
The range is all numbers equal or greater than 5. This is because, even if she does not eventually get fruit juice, she will still incur a cost of 5usd for cups.
