0.773(1972)+8.398= number of water battles consumed in 1972 I think

anonymous · Answer

Would it not be the same considering T is 1...It is since 1971

anonymous · Answer

I was thinking that too, I'm not sure.

its a tricky question

anonymous · Answer

im having trouble with it

anonymous · Answer

N= .773(1 or number of years since 1971) + 8.398   which would be 9.171 gallons

anonymous · Answer

Wow thats quite a coincidence..... 9.171 since 1971 :3

anonymous · Answer

mhmm which would be one year since 1971

anonymous · Answer

yea

anonymous · Answer

The answer isn't 9.171?

anonymous · Answer

If T is the number of years since 1971 and the year is 1972 ..would that not be subtraction? 1972- 1971   which equals 1....    .773(1) = .773 then add that to 8.398 ..which is 9.171
