A 6-pack of juice boxes costs $3.99. A 12-pack costs $5.99.
A 24-pack costs $9.99.
A person wants to buy 158 juice boxes.
What is the least expensive way to do this?
What do 158 juice boxes cost? Justify your answer.​

(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

do you mean add both of the equations together

because if you do the answer is 10x-5

step-by-step explanation:

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.
