Answer:

A. 10.00, so total price is currently 40.00

B. 42.8

C. Total amount is 51.36

Step-by-step explanation:

20% of 50 is 10. Taking off 10% (your discount) would make it 40.

7% of 40 is 2.8. The total amount is now 42.8

20% (your tip) of 42.8 = 8.56.

42.8 + 8.56 = 51.36.

51.36 is your final cost.

Question

RideAnS [48]

Answer:

Step-by-step explanation:

There are 9 letters, which contains 2Qs, 3Ls and 4Bs.

If the 9 letters are distinct, the number of permutations they have will be 9!.

! is the factorial sign.

9! = 9*8*7*6*5*4*3*2*1

HOWEVER, we have some identical elements, so we need to get rid of the permutations of the same letters.

Thus we have:

$\dfrac{9!}{2!*3!*4!} =\dfrac{9*8*7*6*5}{2*3*2*1} = \dfrac{9*4*7*5}{1} = 63*20=1260$

The answer is D
