- The average adult manatee weighs 1,200 pounds. How much do you weigh? How much more does an adult manatee weigh than you weigh?
- The current manatee population is about 2,000 individuals. If half of these manatees are females, then how many female manatees are there?

- It costs $0.75 per pound of vegetation. How much will it cost to feed your manatee for six days?
- You are out taking aerial photos of manatees. When you get back to the laboratory, you develop your pictures and analyze them. You count 12 manatees in one area, 19 manatees in another area, and 15 manatees in the third area where you took pictures. How many manatees did you take pictures of today?
