Wetland Waterpark is a popular end of year field trip destination.
Adams High School and Jefferson High
School both planned trips there. Adams
rented and filled 2 vans and 13 buses with
487 students. Jefferson rented and filed 2
vans and 3 buses with 137 students. Every
van had the same number of students in it
as did the buses. Find the number of
students in each van and each bus.

(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

i got 10.28 but that rounds up to 10.3

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
