It’s 1 that’s in the ten billions
2a+b=-7
5a+b=-13
b=-2a-7
5a-2a-7=-13
3a=-6
a=-2=first number
2(-2)+b=-7
-4+b+-7
b=-3=second
So, one trillion is 1 and twelve zeros, thus 2.4 trillion is 2 trillions and 400 billions or 24 followed by eleven zeros, because the "4" is using up a space.
now, 1 million is 1 and six zeros, thus 100 millions is 100 and six zeros or 1 and 8 zeros.
now, is 2.4 trillions in four months, thus 2.4trillion/4 will give us how many gallons in 1 month.
to find how many households, simply let's divide it by 100 millions
