Grade 7 Percent Applications Worksheet Generator
Extend basic discount, tax, and tip practice into the remaining Grade 7 percent applications: markup and markdown, commissions, fees, simple interest, and percent error. Money problems use integer-cent arithmetic, and percent-error items are constructed to have exact rates.

Exact-construction rule: fraction unit rates stay rational, graph coordinates come from known equations, and money applications use integer cents. No answer key depends on a hidden rounding convention.
Teaching note 1
Identify whether the percentage is an amount to add, subtract, or report separately before calculating.
Teaching note 2
For simple interest, use I = Prt and keep rate and time attached to the correct units.
Teaching note 3
Percent error compares the absolute error with the accepted value, not with the measured value.

Frequently asked questions
Does this replace the existing discount, tax, and tip generator?
No. That tool remains the focused consumer-math practice. This page covers the Grade 7 applications that were still missing.
Can an answer depend on hidden rounding?
No. Money is exact to the cent, and percent-error pairs are constructed to produce exact whole-number rates.
