Introduction to Water Works Revisited


Welcome Back Math Spy!

Please continue gathering information about the water situation on the Isle of Pi.  A spy never knows what information may become crucial to the outcome of a mission.

If you haven't solved Water Works you will have to go back and do that first and take good notes. Then come back here and complete the mission.

If you don't know how to figure out the percent of something, change the percent to a decimal and multiply that decimal by the total. 

For example, if I want to know what 10 % of 50 is, I change 10% to 0.10 and multiply that by 50.

50 X 0.10 = 5.  Five is 10 % of 50.

Click here to continue with the mission.

Right now the water tank has only 50 % of its capacity.  How much water is currently in the water tower?

a. 200.96 cubic meters

d. I don't remember the capacity of the water tower.

The man-made fish pond on the Isle of Pi has lost 10 % of its water due to evaporation.  How much water has evaporated?
