Ed wants to buy a new chair. He found one that he really likes and it is marked down $25\%$ from the original price of $$140$.

1. How much money will he save if he buys the chair?

   Hint (a):

   Think of $25\%$ as $2\left(10\%\right) + 0.5\left(10\%\right)$.
   10% of $140 is $14

   Answer (a):

   $2\left($14\right) + 0.5\left($14\right) = $20 + $7 = $35$ off

2. What is the sale price of Ed's chair?

   Answer (b):

   $$140 - $35 = \:?$

3. Find $75\%$ of $$140$.

   Hint (c):

   Refer to part (a) for help on how to do this part.

4. Explain why the answers for parts (b) and (c) are the same.

   Hint (d):

   $100\% − 25\% = 75\%$
   full price − discount = sale price
