According to the given recipe, Lenny needs 2 parts borax and 2 parts washing soda for every 1 part of soap flakes. This means he needs an equal amount of borax and washing soda.
Since Lenny uses 7 cups of soap flakes, he will need 7 cups of borax and 7 cups of washing soda.
Therefore, the correct answer is 7 cups.
To find the answer, we need to calculate the amount of borax and washing soda combined that Lenny needs.
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 find the amount of borax and washing soda by multiplying the number of parts by the number of cups of soap flakes.
For borax:
2 parts borax * 7 cups of soap flakes = 14 cups of borax
For washing soda:
2 parts washing soda * 7 cups of soap flakes = 14 cups of washing soda
Now we can calculate the combined amount of borax and washing soda:
14 cups of borax + 14 cups of washing soda = 28 cups
Therefore, Lenny needs a combined total of 28 cups of borax and washing soda.
The correct answer is 28 cups.
To determine the number of cups of borax and washing soda combined that Lenny needs, we need to use the ratio specified in the recipe.
The ratio 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 calculate the amount of borax and washing soda required by multiplying that value by the ratio.
To find the quantity of borax, we multiply 7 cups by 2 parts borax:
7 cups x 2 = 14 cups of borax.
To find the quantity of washing soda, we also multiply 7 cups by 2 parts washing soda:
7 cups x 2 = 14 cups of washing soda.
Therefore, Lenny needs a combined total of 14 cups of borax and 14 cups of washing soda.
