Did you know that you can use equations to solve real-life problems? Let's take a look at this scenario: Avaiya has $25 and plans to spend $4 on a book and $3 per day on lunch. a./ To determine how many days Avaiya can buy lunch with this plan, we can create an equation. Let's denote the number of days as "d." Since she spends $3 per day on lunch, the total cost of lunch will be 3d. We also need to consider the $4 spent on the book. Therefore, our equation is: 4 + 3d = 25. b./ By solving this equation, we can find the value of "d." Subtracting 4 from both sides gives us 3d = 21. Then, dividing both sides by 3, we find that d = 7. Thus, Avaiya can buy lunch for 7 days with this plan. Equations are a powerful tool to help us understand and solve various real-world situations like budgeting and planning expenses.
