Answer: 13.6% needed more time but then said no. 25.6% were contacted but said no.
To do this problem, you have to create a tree diagram with all of the possibilities.
The first branch separates with 20% not being contacted and 80% being contacted.
Then, the 80% branch can be broken into 12% saying no and 68% needing more time (multiply by 15% and 85%).
Then, the 68% branch can be broken into 54.4% going and 13.6 not going (multiply by 80% and 20%).
With the tree diagram, just pick the percents that you need.
Answer:
<em>"First, work out the difference (decrease) between the two numbers you are comparing. Decrease = Original Number - New Number. Next, divide the decrease by the original number and multiply the answer by 100. % Decrease = Decrease ÷ Original Number × 100. If the answer is a negative number, this is a percentage increase."</em>
