\r
We’ll explore step-by-step how to:\r
✅ Understand depreciation as a percent of decrease\r
✅ Identify the original value as 100%\r
✅ Determine how much value is lost (the percent decrease)\r
✅ Write an algebraic expression to represent the current value after depreciation\r
✅ Match real-world situations to the correct algebraic expressions\r
\r
You’ll leave this video knowing that:\r
\r
💡 Current Value = Original Value × (1 – Percent of Decrease)\r
\r
This lesson supports helping students connect real-world percent problems to algebraic reasoning.\r
\r
Perfect for 7th-grade students, teachers, or anyone reviewing percent increase and decrease in algebraic form!\r\n
