According to one study, the average American shower lasts for 7.8 minutes and uses 17.2 gallons. Consider a person living in New York City who showers once a day for a year. Find their total cost per year for these showers.3


To calculate the total cost of showers for a person living in New York City who showers once a day for a year, we will need to break the problem into several steps. Here's how to approach it:

### Step 1: Calculate the total water usage per year
The person showers **once a day**, and each shower uses **17.2 gallons** of water.

- Number of showers per year = 365 (since they shower daily).
- Total water used per year = $ 17.2 \, \text{gallons/shower} \times 365 \, \text{showers/year} $.

\[
\text{Total water usage per year} = 17.2 \times 365 = 6,278 \, \text{gallons/year}.
\]

### Step 2: Determine the cost of water in New York City
In New York City, the cost of water and sewer services is typically charged by the gallon. The average cost is approximately **$0.01 per gallon** (which covers both water supply and sewage treatment).

### Step 3: Calculate the total cost
Now, using the cost of **$0.01 per gallon**, we can calculate the total yearly cost for the showers.

\[
\text{Total cost per year} = 6,278 \, \text{gallons/year} \times 0.01 \, \text{USD/gallon}.
\]

\[
\text{Total cost per year} = 62.78 \, \text{USD}.
\]

### Conclusion:
The total cost per year for a person in New York City who showers once a day for a year is **$62.78**.
