Examples Aran has a part-time job as a salesperson. He is paid 2% commission on his total sales. One week his sales wee $7000. How much was his commission?

Examples Find the total cost of a $12.96 shirt after a 6.5% sales tax is added. Total cost = original price + tax Remember when dealing with $ round to the nearest cent.

More examples Shelby receives a 20% employee discount. How much would she pay for a can of paint that normally costs $16.99? Cost = original - discount

Another example Marcus was charged 5.3% simple interest on a loan of $4600. He paid all the money plus interest after 2 years. How much did he pay altogether? I=rtP Add interest to principal to find out the total amount paid.

Yet another example… When Hannah first started working, she was paid $8 an hour. After 6 months, her hourly wage was increased to $8.50. What was her percent of increase?

I know you want to shoot yourself, but just a few more examples… Find the amount of simple interest $900 would earn in 3 years if deposited in an account that paid 3.2% interest. Enrollment dropped from 2325 to 2139 students at Central High. What is the percent decrease
