please help!
Noah knows that his friend Ryan uses 2 small chlorine tablets each week to maintain his 10,000 gallon pool:
1)Write a direct variation equation that relates c and g, where c is the number of chlorine talets and g is pool volume in gallons.
2)How many small chlorine tablets should Noah add each week to is 15,000 gallon pool.

c(g)=2(10,000) and if you want an equivalent, multiply both values by the same number. part b can be solved like (2/10000)=(c/15000), {2(15000)}/10000=c.
