Question

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)

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.

Answer 2

To find out how many cups of borax and washing soda combined Lenny needs, we need to calculate the total parts required for each ingredient.

Given that the recipe calls for 2 parts borax, 2 parts washing soda, and 1 part soap flakes.

If Lenny is using 7 cups of soap flakes, we can determine the total parts required for each ingredient as follows:

Borax: 2 parts x 7 cups soap flakes = 14 cups
Washing soda: 2 parts x 7 cups soap flakes = 14 cups

So, Lenny needs a combined total of 14 cups of borax and washing soda.

Answer 3

To solve this problem, we need to calculate the amount of borax and washing soda required.

The recipe calls for 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 needed based on this ratio.

Let's start with the part that focuses on soap flakes. Since the ratio is 2 parts borax to 1 part soap flakes, we can determine that the total number of parts needed for both borax and washing soda is 3.

Now, we can find the ratio for 2 parts borax to 3 parts total. Since Lenny is using 7 cups of soap flakes, we can set up a proportion:

2/3 = x/7

By cross-multiplying, we get:

2 * 7 = 3x

14 = 3x

Solving for x, we divide both sides of the equation by 3:

x = 14/3

Now that we have the value of x, which represents the amount of borax and washing soda combined, we can substitute it back into the original equation to find the actual amount:

x = 14/3

x = 4.67 cups

So, Lenny needs approximately 4.67 cups of borax and washing soda combined. Since we are looking for the answer in whole cups, we can round it to the nearest whole number, which is 5 cups.

Therefore, Lenny needs 5 cups of borax and washing soda combined.
