The most popular cheese crackers at Craig's Convenience store come in a case of 18 packages. Craig sold 1,950 packages last month. How many cases did he sell? Did he need to open an extra case? If yes, how many packages did he need to take out from the extra case?

108.333

Yes

6 packages

Step-by-step explanation:

Given that:

Case contains 18 packages

Number of packages sold last month = 1950

Number of cases sold last month :

Number of packages / Number of packages per case

1950 / 18

= 108.333

Yes, he needed to open an extra case :

Number of packages sold from the extra case :

1950 - (108 * 18)

1950 - 1944

= 6 packages

(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
