The recipe calls for 2 parts borax for every 1 part soap flakes. Since Lenny is using 7 cups of soap flakes, he will need 2 * 7 = <<2*7=14>>14 cups of borax.
The recipe also calls for 2 parts washing soda for every 1 part soap flakes. Therefore, Lenny will need 2 * 7 = <<2*7=14>>14 cups of washing soda.
Therefore, Lenny needs a total of 14 + 14 = <<14+14=28>>28 cups of borax and washing soda combined. Therefore, the correct answer is 28 cups.
To find out how many cups of borax and washing soda Lenny needs, we need to calculate the total number of cups of soap flakes. According to the recipe, Lenny needs 2 parts borax, 2 parts washing soda, and 1 part soap flakes. Since Lenny uses 7 cups of soap flakes, we can calculate the amount of borax and washing soda required as follows:
Total parts = 2 + 2 + 1 = 5 parts
Cups of borax = (2 parts / 5 parts) * 7 cups = 2.8 cups
Cups of washing soda = (2 parts / 5 parts) * 7 cups = 2.8 cups
Therefore, Lenny needs a combined total of approximately 2.8 cups of borax and 2.8 cups of washing soda.
To find out how many cups of borax and washing soda Lenny needs, we need to calculate the total amount of soap flakes required as mentioned in the recipe.
Given that the recipe calls for 7 cups of soap flakes, we can use the ratio provided in the recipe to determine the amount of borax and washing soda.
The ratio given in the recipe is 2 parts borax, 2 parts washing soda, and 1 part soap flakes. This means that for every 2 cups of borax and washing soda, we require 1 cup of soap flakes.
Since Lenny is using 7 cups of soap flakes, we can determine the amount of borax and washing soda as follows:
For every 1 cup of soap flakes, we need 2 cups of borax and washing soda.
Therefore, for 7 cups of soap flakes, Lenny would need 7 multiplied by 2 cups of borax and washing soda.
Calculating this gives us:
7 cups of soap flakes * 2 cups of borax/washing soda = 14 cups of borax and washing soda.
Therefore, Lenny would need a total of 14 cups of borax and washing soda combined.
Hence, the answer is 14 cups.
