Introduction

As a student, managing one's finances can be a challenging task. In this article, we will explore a real-life scenario where Hannah, a student, spends her daily allowance on lunch and snacks. We will use mathematical equations to model her expenses and find the solution to a problem that arises from her daily spending habits.

The Problem

Hannah spends $4.50\$4.50 each day to buy lunch at her school. After school each day, she buys the same snack. Hannah spends $28.75\$28.75 for lunch and snacks each week. We need to find out how much she spends on snacks each day.

The Equation

Let's denote the cost of the snack as xx. Since Hannah buys the same snack every day, the total cost of the snack for the week is 7x7x (7 days in a week). The total cost of lunch for the week is 5×4.50=22.505 \times 4.50 = 22.50. Therefore, the total cost of lunch and snacks for the week is 22.50+7x22.50 + 7x. We are given that this total cost is equal to $28.75\$28.75. We can write this as an equation:

22.50+7x=28.7522.50 + 7x = 28.75

Solving the Equation

To solve for xx, we need to isolate the variable. We can do this by subtracting 22.5022.50 from both sides of the equation:

7x=28.75−22.507x = 28.75 - 22.50

7x=6.257x = 6.25

Next, we can divide both sides of the equation by 77 to solve for xx:

x=6.257x = \frac{6.25}{7}

x=0.89x = 0.89

Conclusion

Hannah spends $0.89\$0.89 on snacks each day. This is a significant portion of her daily allowance, and she may want to consider reducing her snack expenses to save money for other purposes.

Real-World Applications

This problem can be applied to real-life situations where individuals need to manage their finances. By using mathematical equations to model expenses, individuals can make informed decisions about their spending habits and allocate their resources more effectively.

Introduction

In our previous article, we explored a real-life scenario where Hannah, a student, spends her daily allowance on lunch and snacks. We used mathematical equations to model her expenses and find the solution to a problem that arises from her daily spending habits. In this article, we will answer some frequently asked questions related to Hannah's lunch and snack budget.

Q: What is the cost of the snack that Hannah buys each day?

A: According to our previous calculation, the cost of the snack that Hannah buys each day is $0.89\$0.89.

Q: How much does Hannah spend on lunch each week?

A: Hannah spends $4.50\$4.50 on lunch each day. Since there are 5 school days in a week, she spends a total of 5×4.50=22.505 \times 4.50 = 22.50 on lunch each week.

Q: How much does Hannah spend on snacks each week?

A: We calculated earlier that Hannah spends $0.89\$0.89 on snacks each day. Since there are 7 days in a week, she spends a total of 7×0.89=6.237 \times 0.89 = 6.23 on snacks each week.

Q: What is the total amount that Hannah spends on lunch and snacks each week?

A: We are given that Hannah spends a total of $28.75\$28.75 on lunch and snacks each week. This is equal to the sum of her lunch expenses and snack expenses, which is 22.50+6.23=28.7322.50 + 6.23 = 28.73. This is very close to the given value of $28.75\$28.75, which is due to rounding errors.

Q: How can Hannah reduce her snack expenses?

A: There are several ways that Hannah can reduce her snack expenses. Some possible options include:

  • Buying snacks in bulk and portioning them out
