To make the laundry soap, Lenny needs 2 parts of borax and washing soda for every 1 part of soap flakes. Since he is using 7 cups of soap flakes, he will need 2 * 7 = <<2*7=14>>14 cups of borax and washing soda combined.
To determine the amount of borax and washing soda needed, we need to calculate the total number of parts in the recipe and then multiply that by the number of cups of soap flakes Lenny is using.
The recipe calls for 2 parts borax, 2 parts washing soda, and 1 part soap flakes. This totals to 2 + 2 + 1 = 5 parts.
Since Lenny is using 7 cups of soap flakes, we can calculate the amount of borax and washing soda needed as follows:
7 cups x (2 parts borax + 2 parts washing soda) / 5 parts = 7 cups x 4 parts / 5 parts = 28 cups / 5 = 5.6 cups
Therefore, Lenny needs a total of 5.6 cups of borax and washing soda combined.
To figure out how many cups of borax and washing soda Lenny needs, we first need to determine the ratio of soap flakes to the other ingredients. The recipe states that Lenny needs 2 parts borax, 2 parts washing soda, and 1 part soap flakes.
Since Lenny is using 7 cups of soap flakes, we can determine the quantity of borax and washing soda by multiplying the ratio by the number of cups of soap flakes.
For borax: 2 parts * 7 cups = 14 cups of borax
For washing soda: 2 parts * 7 cups = 14 cups of washing soda
Therefore, Lenny needs a total of 14 cups of borax and 14 cups of washing soda combined.
