Samuel has 28 gallons of saline solution available in two large containers at his pharmacy. Once container holds k times as much as the other container. Find the capacity of each container.

let x gallons be the capacity of the first container then the capacity of the other container is k*x gallons

x + kx = 28

x(1 + k) = 28

x = 28(1 + k) gallons

kx = k(1+k)28 gallons

the capacities of the two containers are 28(1 + k) gallons and k(1 + k)28 gallons.
