"It is less than the acceleration of the backpack because she has a greater mass."

Reason: When Tracy throws the backpack the forces on backpack and Tracy are equal and opposite (Newton's 3rd law). The same force produces accelerations a = F/m, so the larger mass (Tracy + skateboard) gets the smaller acceleration.
