Question

amelia is buying walnuts for a recipe. she already has $1\frac{1}{4}$ cups of walnuts. the recipe calls for $2\frac{3}{4}$ cups of walnuts. how many cups of walnuts does amelia need to buy? let $c$ be the number of cups of walnuts amelia needs to buy. describe the situation with an equation.

Explanation:

Step1: Identify the relationship

Amelia already has \(1\frac{1}{4}\) cups, and she needs to buy \(c\) cups so that the total is \(2\frac{3}{4}\) cups (the recipe's requirement). So the equation is the sum of what she has and what she buys equals the recipe's amount.

Step2: Form the equation

Using the numbers and operations, we have \(1\frac{1}{4}+c = 2\frac{3}{4}\)

Answer:

\(1\frac{1}{4}+c = 2\frac{3}{4}\)
