Question 891369: Kellie's parents give her $2 for each test grade above 90 that she brings home. Which is not a valid statement about the relationship between the number of Kellie's tests with grades over 90 and the amount of money she gets from her parents?
If Kellie brings home 5 tests with grades above 90, she receives $10.
The amount of money Kellie receives depends on the number of tests she has with grades above 90.
The grade Kellie receives on a test depends on the amount of money she earns.
The number of tests with grades above 90 determines how much money she earns.

Think about whether each statement is true.
(Hint: how much money she receives may be an *incentive* to do well on a test, but does not determine the test score.)
