Work Step by Step
Here,
Number of Gallons of water used by arizonas each day is W = 40x
where x = number of Arizonas.
A).
By putting 0, 1000, 2000, 3000, 4000, 5000 as number of arizonas in the given equation, we get answer as 0, 40000, 80000, 120000, 160000, 200000 gallons used per day respectively.
B).
Here W = 120000 gallons per day
i.e. 120000= 40x
i.e. x = $\frac{120000}{40}$ = 3000 Arizonas
