How to calculate the following?
During a period of two weeks, the price of an ounce of silver rose by 25 percent by the end of the first week and then decreased by 20 percent of that price by the end of the second week. If the price of silver was x dollars per ounce at the beginning of the period of two weeks what was the price, in dollars per ounce by the end of the period?
After the increase, you have 1.25x. Then decrease by 20 percent of those, leaving 80% of what you have. 0.80 (1.25) x = 1x, so you have X amount of dollars again.
