 * Wages**


 * Most people earn money by working for a wage.
 * How much money a person earns with a wage depends on two things:
 * How many hours they work
 * How much they are paid for each hour worked

eg: Jonathon works at Woolworths and earns $8.25 an hour. Find how much he will be paid if worked 4 hours on Friday.
 * 4 x $8.25 = $25.00


 * ===** Complete Exercise 3A, page 61. Questions 1, 2, 5 **===


 * To calculate the hourly rate you divide the total wage by the hours worked.

eg: Jonathon earnd $60.60 for working 5 hours. Find the hourly rate.
 * $60.60 ÷ 5 = $12.12


 * ===** Complete Exercise 3A, page 61, Questions 6, **===
 * Wage earners can earn a higher hourly rate for working longer ours (called overtime) or for working on weekends or public holidays (called penalty rates)
 * Overtime or penalty rates are normally either **time and a half** ( one and a half times the hourly rate) or **double time** (two times the hourly rate)

eg: Jonathon gets paid time and a half when works more than 7 hours in a week day or works on a Saturday. He also gets paid double time when he works on a Sunday. He worked 10 hours on Friday and 4 hours on Sunday. He earns $12.36 per hour. Calculate his pay.
 * Normal hours = 7.
 * Time and a half hours = 3
 * Double time = 4
 * (7 x $12.36) + (3 x $18.54) + (4 x $24.72) = $86.52 + $55.62 + $98.88 = $241.02

Piecework

 * Piecework is when a worker is paid according to the number of pieces or articles completed or collected.
 * Examples of piecework include fruit picking, shearing and clothing manufacturing.
 * Such workers generally have greater flexibility of where and when they do this work but they are not usually covered for sickness or other benefits.

eg: Bob is a shearer who earns $3.50 for each sheep he shears. How much would he earn for shearing 1250 sheep?
 * Pay = $3.50 x 1250
 * = $4375
 * Bob should earn $4375

**Commission**

 * Some people employed in sales are paid according to how much they sell.
 * These people are paid a **commission** based on a percentage of sales.
 * Sometimes salespeople are paid a **retainer**, which is a base salary, as well as a commission on sales.

eg: A sales assistant receives a retainer of $310 per week and 25% commission on all sales. How much will the sales assistant earn in a week with $5725 worth of sales?
 * Pay = retainer + commission
 * = $310 + (25% x $5725)
 * = $310 + $1431.25
 * = $1741.25
