## Objective

Students are assessed on the percent unit.

#### Big Idea

This test covers all aspects of percent problems addressed in the unit.

## The Test

50 minutes

Here is an answer key.  I tried to make sure to include every example mentioned in the standard 7.rp.3:

"Use proportional relationships to solve multistep ratio and percent problems. Examples: simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error."

I did not however include percent error.  Also 7.EE.2 is represented for equivalent expressions.

Problem 1 - Apply percents of increase and decrease

Problem 2 - Find percent of change

Problem 3 - Find total given a part and percent

Problem 4 - Find a commission

Problem 5 - Find a sale price

Problem 6 - Find a markup

Problem 7 - Find a total with sales tax

Problem 8 - Simple Interest

Problem 9 - Equivalent expressions

Problem 10 - Find original price

Problem 11 - Equivalent expressions

Problem 12 - Equivalent expressions (sale price)

Correct answer: Any two of the three expressions --->  d - 0.32d; 0.68d; d(1-0.32)

Problem 13 - Equivalent expressions (total with sales tax)

Correct answer: Any two of the three expressions ---> x + 0.09x; 1.09x; x(1+0.09)

## Scoring

The assessment is worth a total of 15 points.

Problems 1-11 are each worth 1 point.

Problem 12 is worth 2 points for 2 valid expressions.

Problem 13 is worth 2 points for 2 valid expressions.

11 out of 15 points would be considered proficient

12+ out of 15 points would be considered mastery.
