Introduction

Inequalities are mathematical expressions that compare two values, often used to describe relationships between variables. In real-world scenarios, inequalities can be used to model various situations, such as the amount of ingredients needed for a recipe. In this article, we will explore how to use inequalities to find the number of tablespoons of flour needed for a bread recipe, given the variation in humidity levels.

The Problem

Henry's bread recipe calls for 3 cups of flour, with a variation of up to 4 tablespoons depending on the humidity level. There are 16 tablespoons in 1 cup. We need to find the number of tablespoons of flour, denoted as $t$ , that should be used in the recipe.

Converting Cups to Tablespoons

Since there are 16 tablespoons in 1 cup, we can convert the 3 cups of flour to tablespoons by multiplying 3 by 16.

# Convert cups to tablespoons
cups = 3
tablespoons_per_cup = 16
total_tablespoons = cups * tablespoons_per_cup
print(total_tablespoons)

This will give us the total number of tablespoons of flour needed for the recipe, which is 48 tablespoons.

Accounting for Humidity Variation

However, the recipe allows for a variation of up to 4 tablespoons depending on the humidity level. This means that the actual number of tablespoons of flour needed could be anywhere from 44 tablespoons (48 - 4) to 52 tablespoons (48 + 4).

Writing the Inequality

To find the number of tablespoons of flour, denoted as $t$ , we can write an inequality that represents the range of possible values. Since the actual number of tablespoons of flour needed could be anywhere from 44 to 52, we can write the inequality as:

44 ≤ t ≤ 52

Solving the Inequality

The inequality 44 ≤ t ≤ 52 represents the range of possible values for $t$ . Since we are looking for the number of tablespoons of flour, we can conclude that the number of tablespoons of flour needed for the recipe is between 44 and 52.

Conclusion

In this article, we used inequalities to find the number of tablespoons of flour needed for a bread recipe, given the variation in humidity levels. We converted cups to tablespoons, accounted for the humidity variation, and wrote an inequality to represent the range of possible values. By solving the inequality, we found that the number of tablespoons of flour needed for the recipe is between 44 and 52.
