Question

Erick sold 2 pounds of walnuts and 4 pounds of almonds for $28. The next day, he sold4 pounds of walnuts and 3 pounds of almonds for $31. Which system of equations canbe used to determine the cost per pound of walnuts x, and the cost per pound ofalmonds, y?F 2x - 4y = 284x + 3y = 31G 2x + 4y = 284x + 3y = 31H 2x + 4y = 314x + 3y = 28) 4x + 3y = 282x + 4y = 31

Answer 1

Let the selling price for walnuts be x and the selling price for the almonds be y.

On the first day, Erick sold 2 pounds of walnuts and 4 pounds of almonds for $28. This implies that

`\begin{gathered} 2x\text{ + 4y =28 } \\ \text{equation 1} \\ \end{gathered}`

On the second day, 4 pounds of walnuts and 3 pounds of almonds for $31.
