Noah knows that his friend Ryan uses 2 small chlorine tablet

Noah knows that his friend Ryan uses 2 small chlorine tablets each week to maintain his 10,000 gallon pool.

A.) Write a direct variation equation that relates c and g, where c is the number of chlorine tablets and g is pool volume in gallons.

B.) How many small chlorine tablets should Noah add each week to his 15,000 gallon pool? Show calculations please.

Solution

A) Ryan adds,each week, 2 small chlorine tablets to his 10000 gallon pool. The required direct variation equation is c =( 2/1000)g .

B) when g = 15000, we have c = (2/10000)15000 = 3. Thus Noah should add ,each week, 3 small chlorine tablets to his 15000 gallon pool.
