A glass was filled with 40 ounces of water, and 0.01 ounce of the water evaporated each day during a 20-day period. What percent of the original amount of water evaporated during this period?	Choose one:
A) 0.005% B) 0.02% C) 0.5% D) 5% E) 20%
We are given that 0.01 ounces of water evaporated EACH DAY. Furthermore, we know that this process happened over a 20-DAY PERIOD. To calculate the total amount of water that evaporated during this time frame we need to multiply 0.01 by 20. This gives us:   0.01 x 20 = 0.2 ounces   Finally, we are asked for “What percent” of the original amount of water evaporated during this period. To determine this percentage, we have to make sure we translate the expression correctly. We can translate it to:   (Amount Evaporated/Original Amount) x 100%   (0.2/40) x 100%   = 0.5%   Answer 0.5%
