1. Bell Work Complete on the back of assignment and turn assignment and bell work into tray. State whether each percent of change is a percent of increase or decrease. Then find the percent of change. Round to the nearest whole percent. 1)O: 842) O: 47 N: 96 N: 18 N: 96 N: 18 3) Find the discounted price of a tent with a price of $89 and a discount of 15%. 4) Find the final price of a pair of hiking boots with a price of $78, a discount of 10%, and tax 6%. 5) On July 1, a stock sold for $46 per share, and on August 1, it sold for $48.30 per share. What was the percent of change in the price of the stock?

2. The formula s = (w – 10e)/m is often used by placement services to find keyboarding speeds. In the formula, s represents the speed in words per minute, w represents the number of words typed, e represents the number of errors, and m represents the number of minutes typed. The formula s = (w – 10e)/m is often used by placement services to find keyboarding speeds. In the formula, s represents the speed in words per minute, w represents the number of words typed, e represents the number of errors, and m represents the number of minutes typed. –Solve the formula for e. –If Miguel typed 410 words in 5 minutes and received a keyboard speed of 76 words per minute, how many errors did he make?
