Problem-solving using Venn diagram is a widely used approach in many areas such as statistics, data science, business, set theory, math, logic and etc.Solution #1: Use of one variable leading to a linear equation. Let x be the number of pounds of cashews. So, 150 - x will represent the number of almonds. Since each pound of the mixture costs 3 dollars, 150 pounds will cost 3 × 150 = 450 dollars. Cost of cashews + cost of almonds = 450. 2 × x + (150 - x) × 5 = 450. 2x + 150 × 5 - x × 5 = 450.Online math solver with free step by step solutions to algebra, calculus, and other math problems.
