What is the product of any integer and -1? A. The product is the opposite of the integer
B. The product is the integer unchanged
C. The product is positive
D. The product is negative

The answer is A (or the first one)

Step-by-step explanation:

So we will have, x, as a random number

Example with a positive number: (x*-1= -x)

Example with a negative number: (-x*-1=x)

So you can tell that if I did it with a positive number, it turns negative, and a negative number goes positive.

Example of opposites: -5 and 5, or 3 and -3

Lets say x was 5, the first example would be: (5*-1=-5)

The second example would be: (-5*-1=5)

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
