Answer 1

The recipe calls for 2 parts borax, 2 parts washing soda, and 1 part soap flakes. This means that for every 1 part of soap flakes, there are a total of 4 parts of the other ingredients (2 parts borax + 2 parts washing soda).

Since Lenny is using 7 cups of soap flakes, we can determine the total number of parts for borax and washing soda combined:

1. From the recipe, 1 part of soap flakes corresponds to 4 parts of the other ingredients.
2. Therefore, \( 7 \text{ cups soap flakes} \times 4 = 28 \text{ cups of borax and washing soda combined} \).

Thus, Lenny needs 28 cups of borax and washing soda combined.
