## Sample Levels (out of 6)

Do not put multiplication signs between a variable and its coefficient. (e.g., Use "5m" instead of "5 × m")

1.
You burn 5 calories every minute you exercise.

A. Which variable(s) are independent?
(Check all that apply.)
 number of calories you burn
 number of minutes you exercise
 calories burned per minute

B. Which variable(s) are dependent?
(Check all that apply.)
 number of minutes you exercise
 number of calories you burn
 calories burned per minute

C. Write an equation that expresses the situation.
Let c be the number of calories you burn.
Let m be the number of minutes you exercise.
