Answer 1

The recipe calls for a total of 5 parts: 2 parts borax, 2 parts washing soda, and 1 part soap flakes, which totals 2 + 2 + 1 = 5 parts.

If Lenny uses 7 cups of soap flakes, which is 1 part, we can determine the amount for the other ingredients.

Since 1 part corresponds to 7 cups, we can calculate the other parts:

• Borax: 2 parts = 2 × 7 cups = 14 cups
• Washing soda: 2 parts = 2 × 7 cups = 14 cups

Now, to find the total amount of borax and washing soda combined: 14 cups (borax) + 14 cups (washing soda) = 28 cups

So, Lenny needs 28 cups of borax and washing soda combined. The answer is 28 cups.
