1. Big Idea Many types of questions involving percents can be answered by solving an equation of the form ax = b Goal Solve three basic percent problems by translating them into equations.

4. Write an equation for each situation then solve. 1. 4% of what number is 76? To write the equation, make a direct translation for the words and %. 2. What percent of 210 is 33.6?

5. 3.Chuck wants to buy a pair of jeans costing $44.50. He knows he will be charged 4.5% sales tax on the jeans. Find the total cost of the jeans including the sales tax. 4.A bicycle normally costs $425, but is on sale for 20% off. What is the sale price? Sale price = bicycle – discount (% of bike)

6. Sale price = bicycle – discount(% of bike) The price of the bicycle represents 100% of the bicycle and the discount is 20% of the bicycle, the sale price is 100% - 20% of the bicycle: Total cost = jeans + tax(% of jeans) The price of the jeans represents 100% of the jeans and the tax is 4.5% of the jeans, the total cost is 100% + 4.5% of the jeans:
