Jackie walks onto an elevator floor at level 2. The elevator goes up 3 floors, down 8 floors, and goes back up 11 floors. What floor is Jackie on now? Choose the correct equation and sum.

• 2 + 3 + (-8) + 11 = 8

• 2 + 3 + (-8) + (-11) = -3

• 2 + (-3) + (-8) + 11 = 5

• 2 + 5 + (-8) + 11 = 10

A free fall ride takes riders up to 75 feet before dropping them 55 feet, then brings them back up another 95 feet. How high above ground level are the riders at this point?

Choose the correct equation and answer.

• 75 + (-55) + 95 = 115

• 75 + 55 + (-95) = 35

• (-75) + 55 + 95 = 75

• 75 + 55 + 95 = 225
