Question 2
A park ranger uses two drones to observe wildlife. After letting the drones hover at the same height for a while, she decreases the height of the first drone by 38 feet in order to take pictures. She also
decreases the height of the second drone, but only by 20% of the decrease in height of the first drone.
Which THREE methods could be used to find the change in height, in feet, of the second drone?
A Multiply —38 3/4 by 1/5
B Multiply —38.75 by 0.2
C Multiply -38.75 by 0.2. Then add 0.75
D Multiply -38 by 1/10. Then multiply by 1/2
E Multiply -38 by 1/5. Then multiply-by —3/4 by 1/5. Add the products.
