14 cups

The correct answer is 28 cups.

Since the recipe calls for 2 parts borax and 2 parts washing soda, the total amount of borax and washing soda combined is 2 + 2 = 4 parts.
Therefore, if Lenny uses 7 cups of soap flakes, he will need 4 x 7 = 28 cups of borax and washing soda combined.

so the answer is 7?

No, the answer is not 7 cups. The correct answer is 28 cups.

To find the number of cups of borax and washing soda combined that Lenny needs, we need to calculate it based on the ratio provided in the recipe.

The recipe calls for 2 parts borax, 2 parts washing soda, and 1 part soap flakes. This means that for every cup of soap flakes, Lenny needs 2 cups of borax and 2 cups of washing soda.

Since Lenny is using 7 cups of soap flakes, we can calculate the amount of borax and washing soda he needs by multiplying the number of cups of soap flakes by the respective ratios:

Borax: 7 cups of soap flakes * 2 parts borax / 1 part soap flakes = 14 cups of borax
Washing soda: 7 cups of soap flakes * 2 parts washing soda / 1 part soap flakes = 14 cups of washing soda

Therefore, Lenny needs a combined total of 14 cups of borax and 14 cups of washing soda.
