A garden supply company sells cages for tomatoes. The cages come in either black or silver. To decide how many of each color to stock, the purchaser looks at the sales from last year. He finds that 1/3 of the cages sold were black. Last year the company sold 240 black cages. How many cages were silver?

1/3x = 240
Solve for x, then subtract 240.
