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?

A. 7
B. 28
C. 21
D. 14

Answer 1

[AI-generated answer — Explain Bot]

To find the number of cups of borax and washing soda combined, we need to determine the ratio of soap flakes to borax and washing soda. The recipe states that Lenny needs 2 parts borax and 2 parts washing soda for every 1 part soap flakes.

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

Since Lenny is using 7 cups of soap flakes, he will need 2 times 7 cups of borax and washing soda combined.

2 times 7 is equal to 14.

Therefore, Lenny needs 14 cups of borax and washing soda combined.

Therefore, the correct answer is option D. 14.

Answer 2

[AI-generated answer — Bot GPT 3.5]

The recipe states that Lenny needs 2 parts borax for every 1 part of soap flakes. Therefore, if he is using 7 cups of soap flakes, he will need 2 * 7 = <<2*7=14>>14 cups of borax.

The recipe also states that Lenny needs 2 parts washing soda for every 1 part of soap flakes. Therefore, he will need 2 * 7 = <<2*7=14>>14 cups of washing soda.
The total amount of borax and washing soda combined that Lenny needs is 14 + 14 = <<14+14=28>>28.
So, the answer is B. 28.

Answer 3

[AI-generated answer — Step-by-Step Bot]

The recipe requires 1 part of soap flakes, 2 parts of borax, and 2 parts of washing soda. If Lenny uses 7 cups of soap flakes, we can calculate the amount of borax and washing soda needed as follows:

1 part soap flakes = 7 cups
2 parts borax + 2 parts washing soda = 4 parts in total

To find the total amount of borax and washing soda, we divide the total number of parts by the number of parts in the recipe:

Total parts = 7 cups (soap flakes) x 4 parts (total) = 28 cups

Since borax and washing soda are in equal parts, we divide the total cups by 2 to find the number of cups needed for each:

Total cups / 2 = 28 cups / 2 = 14 cups

Therefore, the answer is D. 14.

Apologies for the confusion in my previous response. I made an error in interpreting the ratio.

The recipe calls for 2 parts borax, 2 parts washing soda, and 1 part soap flakes.

If Lenny uses 7 cups of soap flakes, we need to determine the corresponding amounts of borax and washing soda.

The total number of parts in the recipe is 2 (borax) + 2 (washing soda) + 1 (soap flakes) = 5 parts in total.

To find the number of cups of borax by proportion, we take 2/5 (2 parts borax out of 5 parts in total) of the total amount of cups needed:

Cups of borax = (2/5) * 7 cups = 2.8 cups

To find the number of cups of washing soda by proportion, we also take 2/5 (2 parts washing soda out of 5 parts in total) of the total amount of cups needed:

Cups of washing soda = (2/5) * 7 cups = 2.8 cups

So, the answer is not one of the given options. My previous response was incorrect. The correct answer is not listed. I apologize for the confusion caused.
