Worksheet

Algebra in Real Life Worksheet

This worksheet includes real-life scenarios that require the use of algebra to solve. Each group will be assigned a scenario to work on together.

Scenario 1: Budgeting - Calculate the monthly budget required for a family of four given their expenses and income.

Use algebraic equations to represent the total income and expenses, and solve for the budget.

Scenario 2: Construction - Determine the amount of materials needed to build a rectangular patio of a given size.

Use algebraic formulas for area and perimeter to calculate the materials required.

Scenario 3: Technology - Calculate the speed of data transfer given the file size and time taken to transfer.

Use algebraic equations to represent the relationship between file size, transfer speed, and time.
