    Each 15 minute shower is going to use 15 times 2.3 gallons. Each week, there are going to be 6 of those- so 6 times (15X 2.3). There are 52 weeks in a year. It's just multiplication.

    One shower length is 15 minutes so the total amount of water used in is 15 time of 2.3 gallons. If the average 6 showers will be taken in the week so it 6 times of the total amount of water used in a shower it will give you total water used in a week. And there are 52 weeks in a year so it 52 times of total water used in a week. so simple multiplication and you will get the answer.

    write out all the units when you multiply to make sure you cancel out everything properly

    2.3 gallons/minute * 15 minutes/shower * 6 showers/week * 52 weeks/year = xxx gallons/year

    see that the minutes, showers, weeks cancel out and you are left with gallons/year
