Fractions: Computing the Total Purchase Cost

In this interactive, real-world budgeting worksheet, 7th grade students visit a virtual supermarket with a $100 budget to purchase a list of grocery items. Using a cost card that lists realistic prices per unit (e.g., per pound, gallon, or piece), students must calculate the total cost of each item based on quantity, sum the total, and determine whether they can afford all items — or if they’ll need extra funds.

This activity supports Common Core Math Standards 7.RP.A.1, 7.RP.A.2, and 7.EE.B.3 by engaging students in:

• Unit rate calculations involving decimals
• Real-life proportional reasoning
• Multi-step problem solving with money
• Budget analysis based on cumulative totals
• Bar graph interpretation to identify the most expensive item

The worksheet is auto-graded, giving instant feedback on cost calculations and encouraging self-correction. A final extension question asks students to analyze a bar graph comparing item costs.

Key Features:

• 🧮 Realistic unit rates and quantities
• 💰 Budget decision-making scenario
• 🔄 Auto-graded responses for immediate feedback
• 📊 Bar graph data interpretation
• ✍️ Great for classwork, homework, or financial literacy warm-ups
