Question 2718
Total use in gallons per person per day = 42 gallons

Percentage going in flushing = 47%

Gallons going total per person per day in flushing total = 
=(47/100)*42
=19.74 gallons

Gallons used per average flush = 4 gallons

Therefore average number of flushes per person per day =
= 19.74/4
= 4.935
= ~5 flushes

<B>Thus this figure indicates an average of 5 flushes per day per person.</b>

Hope this helps,
