Question

Selena's favorite chocolate chip cookie recipe calls for 1 teaspoon of salt for every 2 1/4 . In Deepak’s recipe, the relationship between teaspoons of salt (t) and cups of flour (c) is shown in the graph below. Whose cookies are saltier?

Answer 1

To determine whose cookies are saltier, we compare the ratio of teaspoons of salt to cups of flour in each recipe. Deepak's cookies are saltier than Selena's cookies.

Step-by-step explanation:

To determine whose cookies are saltier, we need to compare the ratio of teaspoons of salt to cups of flour in each recipe. Selena's recipe calls for 1 teaspoon of salt for every 2 1/4 cups of flour.

Deepak's recipe can be represented by a graph, which shows the relationship between teaspoons of salt (t) and cups of flour (c).

By comparing the ratios, we can determine whose cookies are saltier.

Let's say Deepak's recipe has a ratio of 1 teaspoon of salt (t) to 3 cups of flour (c).

To compare the two ratios, we can write them as fractions: Selena's ratio is 1/2.25 and Deepak's ratio is 1/3.

We can simplify these fractions to get 2/4.5 and 1/3. Both fractions have the same numerator, but Selena's fraction has a larger denominator.

Since Selena's fraction has a larger denominator, it means that for every cup of flour, her recipe uses less salt compared to Deepak's recipe. Therefore, Deepak's cookies are saltier than Selena's cookies.
