School Holidays:

Codes and Ciphers are ways of scrambling up words to make them impossible to understand. Julius Caesar a Roman soldier developed what is known as the Caesar Cipher to send letters to back to Rome when he was away fighting . In the Caesar Cipher each letter in the message is replaced by a letter 3 places further along. So A is replaced by D, C is replaced by F and so on. This is shown in the picture below

Instructions

• We are trying to problem solve if Ms Jansz will be able to buy a house. To figure that out we have to find out how much I earn a year before and after tax. Then looking at property areas that I can afford. Every fortnight I earn $1500. So every week I earn $750.

2. Then the government taxes me 30% how much do I get in hand at the end of year.

3. Also, how much do I get a fortnight after being taxed?
