A glass was filled with 10 ounces of water, and 0.05 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 the correct choice from the following answers
A) 0.002 % B) 0.02 % C) 0.2 % D) 2 % E) 10 %

Rationale: "we are given that 0.05 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 0.05 by 20 . this gives us : 0.05 x 20 = 1 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 % ( 1 / 10 ) x 100 % ( 10 / 100 ) x 100 % = 10 % answer e"
Answer: E
