Question

an order of cashews and peanuts weighs 11 pounds and costs $31. cashews: $3.00 per pound peanuts: $2.50 per pound how many pounds of cashews and peanuts are in this order? finally, subtract p from both sides of the equation to rewrite this equation in terms of c. \\(\

$$\begin{cases} 3c + 2.5p = 31 \\\\ c + p = 11 \\end{cases}$$

\\) \\(\

$$\begin{align} c + p &= 11 \\\\ -p \\quad \\quad & -p \\\\ \\square &= \\square \\end{align}$$

\\)

Explanation:

Step1: Subtract $p$ from left side

$c + p - p = c$

Step2: Subtract $p$ from right side

$11 - p$

Answer:

$c = 11 - p$
