\(\displaystyle Another \ way, \ to \ wit:\)
\(\displaystyle \$140.00-\$58.20 \ = \ \$81.80\)
\(\displaystyle \frac{\$81.80}{\$140.00} \ \dot= \ .584285714286 \ \dot= \ 58.4\%\)

Scott is going to Florida in March. On line, he finds a room in a hotel that is normally $150.00 per night for $50.00 per night. What is the rate of discount on the room?
\(\displaystyle Hence, we \ easily \ see \ that \ the \ room \ is \ \$100.00 \ less \ than \ usual, \ ergo \ we \ save \ {\$100.00/\$150.00\)
\(\displaystyle or \ \frac{2}{3} \ which \ is \ the \ discount, \ 66\% \ of \ the \ usual \ price \ of \ the \ room \ (\$150.00).\)
