Mrs. king gets a 15% discount on merchandise bought in the store where she works. last week she bought several items that totaled $57.25 before the discount. how much did she have to pay using her discount? round off the amount to the nearest cent.

48.6625 before rounding, I'm sure the instruction told you where it preferred you to round.

Step-by-step explanation:

1. Convert percent value to a decimal.

The way to do this is by moving the period at 15.00 two places to the left.

2. Now that you have the decimal .15, multiply it by Mrs. King's subtotal (57.25).

you should get 8.5875.

3. Subtract the discount amnt. (8.5875) from the subtotal (57.25).

You should get 48.6625.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
