Lenny is making his own laundry soap. The recipe calls for two parts for borax two parts, washing soda and one part soap flakes if Lenny uses 7 cups of soap flakes how many cups of borax and washing soda combined does he he need

Answer 1

Lenny's recipe consists of a ratio of 2 parts borax, 2 parts washing soda, and 1 part soap flakes. This means for every 1 part of soap flakes, he needs 2 parts of borax and 2 parts of washing soda.

Since Lenny is using 7 cups of soap flakes, we can set up the following relationship based on the parts:

1 part soap flakes = 7 cups 2 parts borax = 2 * 7 cups = 14 cups 2 parts washing soda = 2 * 7 cups = 14 cups

Now, to find the total amount of borax and washing soda combined:

Total = Borax + Washing soda = 14 cups + 14 cups = 28 cups

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