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)

Question

O 21 cups

O 7 cups

14 cups

28 cups

Answer 1

To find the total amount of borax and washing soda needed, we add together the amounts of each ingredient.

First, we calculate the amount of borax needed:
2 parts borax = 2 * 7 cups = 14 cups

Next, we calculate the amount of washing soda needed:
2 parts washing soda = 2 * 7 cups = 14 cups

Finally, we add the amounts of borax and washing soda together:
14 cups + 14 cups = 28 cups

Therefore, Lenny needs a total of 28 cups of borax and washing soda combined.
