Step-by-step explanation:

Solving the Problem

Breaking it Down

We're given

  • there are 6 people,
  • each person uses 72L of water over 1 month,
  • the water cost is $0.20 per liter (L).

We're asked to find the total amount of money spent on water.

Calculating the Final Answer

The total amount of water used in one month is the product of the number of liters used by one person and the total amount of people that used it.

So,

                                                72 x 6 = 432.

To find the total amount of money that's spent on water for the entire month (432 liters), we multiply the total amount of liters used by the unit cost!
So,

                                          432 x 0.20 = 86.40.
