Question

The Hernández family reads their water meter which reads 4,323 thousand gallons. The previous month the meter reading was 4,311 thousand gallons. What was the total water usage for the month?

4,323 Tgal
12 Tgal
11 Tgal
4,311 Tgal

Answer 1

To calculate the total water usage for the month, subtract the previous month's meter reading from the current month's reading.

Current meter reading: 4,323 thousand gallons
Previous meter reading: 4,311 thousand gallons

Water usage = Current reading - Previous reading
Water usage = 4,323 Tgal - 4,311 Tgal
Water usage = 12 Tgal

The total water usage for the month is **12 Tgal**.
