Lenny is making his own laundry soap. The recipe calls for 2 parts borax, 2 parts washing soda, and 1 part soap flakes. If Lenny uses 7 cups of soap flakes, how many cups of borax and washing soda combined does he need?(1 point) Responses 14 cups 14 cups 21 cups 21 cups 7 cups 7 cups 28 cups

Answer 1

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

If Lenny uses 7 cups of soap flakes, we can determine the amounts of borax and washing soda needed:

• For soap flakes: 1 part = 7 cups
• Therefore, the amount of borax needed = 2 parts = 2 × 7 cups = 14 cups
• The amount of washing soda needed = 2 parts = 2 × 7 cups = 14 cups

Now, we add the amount of borax and washing soda together:

14 cups (borax) + 14 cups (washing soda) = 28 cups

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

The correct response is: 28 cups.
