Answer: 9

Step-by-step explanation:

When you multiply 9*9, you get 81 whose sum is 9 (8+1)

Likewise, 9*8=72( 7+2=9)

I am the number '9'

To prove:

On multiplying 9 with different numbers, the sum of the digits of its product is always 9. Let's see;

9 * 2 = 18

where (1 + 8 = 9)

Now, multiplying it by 3

9 * 3 = 27

where (2 + 7 = 9)

Similarly,

9 * 4 = 36

where (3 + 6 = 9)

9 * 5 = 45

where (4 + 5 = 9)

9 * 6 = 54

where (5 + 4 = 9)

9 * 7 = 63

where (6 + 3 = 9).

Thus, option b i.e. 9 is the correct answer.

I believe the answer is $2.25

Step-by-step explanation:

To figure this out, first you need to find 25% as a decimal. 25% as a decimal is .25 . Then, you multiply 9 by .25 . 9 * .25 = $2.25. You are saving $2.25 with the discount.
