According to the recipe, Luis needs 1 cup of almonds for every 1 cup of chocolate chips. Since he is using 3 cups of chocolate chips, he will need 3 cups of almonds. Therefore, he will need 3 cups of almonds.
If the recipe calls for 1 cup of almonds for every 1 cup of chocolate chips, and Luis uses 3 cups of chocolate chips, then he will need 3 cups of almonds.
To find out how many cups of almonds Luis will need, we need to use the ratio provided in the recipe: 1 cup of almonds for every 1 cup of chocolate chips.
Since Luis is using 3 cups of chocolate chips, we can set up a proportion to solve for the number of cups of almonds:
1 cup almonds / 1 cup chocolate chips = x cups almonds / 3 cups chocolate chips
To solve for x, we can cross multiply:
3 cups chocolate chips * 1 cup almonds = 1 cup chocolate chips * x cups almonds
3 cups almonds = x cups almonds
Therefore, Luis will need 3 cups of almonds for 3 cups of chocolate chips. However, according to the options provided, the rounded answer to the nearest tenth would be 0.4 cup.

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?
Since the recipe calls for 2 parts borax, 2 parts washing soda, and 1 part soap flakes, the ratio of borax to washing soda to soap flakes is 2:2:1.
Let's assume that Lenny needs x cups of borax and x cups of washing soda. According to the ratio, he will need 2x cups of borax and 2x cups of washing soda.
Since Lenny is using 7 cups of soap flakes, which is 1 part in the ratio, we can set up a proportion to solve for x:
1 part soap flakes / 7 cups soap flakes = 2 parts borax + 2 parts washing soda / 2x cups borax + 2x cups washing soda
To solve for x, we can cross multiply:
(2x cups borax + 2x cups washing soda) = (1 part soap flakes * 2x cups soap flakes) / (1 part soap flakes)
2x cups borax + 2x cups washing soda = 2x cups soap flakes
2x cups borax + 2x cups washing soda = 7 cups soap flakes
Since we know that Lenny is using 7 cups of soap flakes, we can substitute it into the equation:
2x cups borax + 2x cups washing soda = 7
Now, we can solve for x:
4x cups = 7
x = 7/4
x = 1.75
Therefore, Lenny will need 1.75 cups of borax and 1.75 cups of washing soda combined.

Since the recipe calls for 2 parts borax, 2 parts washing soda, and 1 part soap flakes, the ratio of borax to washing soda to soap flakes is 2:2:1.
This means that for every 2 cups of borax, Lenny will need 2 cups of washing soda and 1 cup of soap flakes.
Since Lenny is using 7 cups of soap flakes, we can calculate the amount of borax and washing soda needed.
For every 1 cup of soap flakes, Lenny will need 2 cups of borax and 2 cups of washing soda.
Therefore, if Lenny uses 7 cups of soap flakes, he will need:
2 cups of borax * (7 cups of soap flakes / 1 cup of soap flakes) = 14 cups of borax
2 cups of washing soda * (7 cups of soap flakes / 1 cup of soap flakes) = 14 cups of washing soda
Therefore, Lenny will need a combined total of 14 cups of borax and washing soda.
