If something costed $20 but was 15% off how much would you pay
for it?

$17.00

Step-by-step explanation:

$17 dollars

Step-by-step explanaion:

15% of $20=3

20-3=17

(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

answer: t=3
