Question

ok, best way to solve these is to use algebra.

so lets call the capacity of the tank c gallons.

this means that initially the tank contained c/3 gallons as it was 1/3 full.

ok so far?

good, you are then told that when 10 gallons are added it become 3/4 full.

asnaseer · Answer

this translates to:

3c/4 = c/3 + 10
