The recipe calls for 2 parts borax to 1 part soap flakes. Since Lenny is using 7 cups of soap flakes, he will need 2 times the amount of borax. Therefore, he needs 2 * 7 = 14 cups of borax.
The recipe also calls for 2 parts washing soda to 1 part soap flakes. Similarly, Lenny will need 2 times the amount of washing soda. Therefore, he needs 2 * 7 = 14 cups of washing soda.
In total, Lenny needs 14 cups of borax and 14 cups of washing soda, which combined is 14 + 14 = 28 cups.
So the correct answer is 28 cups.
