Gas costs $2.09 and you figure you will use 30 gallons on your trip with your two friends. you will stay 4 nights at a hotel (one room) for $98 a night, and spend $25 each per day on food for 5 days. what is the total cost of your trip?

Just took the test its 829.70

Step-by-step explanation:

the one on the bottom left

step-by-step explanation:

all of the other ones have a specific pattern

(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
