James bought some cans of sardines and tuna in the ratio of 4:5. A total of 22 cans of sardines and 1/2 of the cans of tuna were used. In the end, the ratio of the cans of sardines to the cans of tuna became 1:2. Find the number of cans of sardines that James bought at first.

S : T = 4 : 5

(4x-22)/(5x/2) = 1/2          x = 8

cans of sardines = 4x
