Answer:

Total = 4.8 * 10^{10}

Step-by-step explanation:

Given

h = 1.2 * 10^8 --- households

g = 400 --- gallons

Required

The number of households

To do this, we simply multiply the average households by the gallons.

Total = g* h

Total = 400 * 1.2 * 10^8

Total = 480 * 10^8

Rewrite as:

Total = 4.8 * 10^2 * 10^8

Total = 4.8 * 10^{10}
