An item with an original price of d dollars has its price increased by x percent in April and then decreased by x percent in May
. The resulting price is 4 percent less than the original price. What is the value of x?
1 answer:
So the final price would be:
<span>d(100+x)(100-x) / 100² </span>
<span>= d(100² - x²) / 100² </span>
<span>= d(1 - (x/100)²)</span>

Answer:
Pace in miles per hour = ![6\frac{18}{33}\ miles\ per\ hour](https://tex.z-dn.net/?f=6%5Cfrac%7B18%7D%7B33%7D%5C%20miles%5C%20per%5C%20hour)
Step-by-step explanation:
Distance ran in 33 minutes = ![3\frac{3}{5}\ miles = \frac{18}{5}\ miles](https://tex.z-dn.net/?f=3%5Cfrac%7B3%7D%7B5%7D%5C%20miles%20%3D%20%5Cfrac%7B18%7D%7B5%7D%5C%20miles)
33 minutes = ![\frac{18}{5}\ miles](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B5%7D%5C%20miles)
1 minute = ![\frac{18}{5}*\frac{1}{33}\ miles](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B5%7D%2A%5Cfrac%7B1%7D%7B33%7D%5C%20miles)
60 minutes = ![\frac{18}{5*33}*60\\](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B5%2A33%7D%2A60%5C%5C)
60 minutes =
miles
Unit rate = ![6\frac{18}{33}\ miles\ per\ hour](https://tex.z-dn.net/?f=6%5Cfrac%7B18%7D%7B33%7D%5C%20miles%5C%20per%5C%20hour)
