9. chet is camping with 75 people from his after-school club. a tent

can hold up to 8 people. how many tents are needed? explain

your thinking

Step-by-step explanation:

Let be "x" the number of tents needed for 75 people.

According to the information provided in the exercise, a tent can hold up to 8 people.

Then, knowing that Chet is camping with 75 people from his after-school club, you can set up the following proportion:

Finally, you must solve for "x" in order to find its value.

Then you get:

You need to round this result. Since 9 tents won't be enough (because ):

(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
