Opening video:

Video clip from Father of the Bride



*What does Steve Martin want?
*How would the cashier do this (if Steve was not put into jail)?
*What could Steve have done instead?

Strips from last class:
20% strip - ratio of 100:20:80 relates to 5:1:4 (What is the relationship described?)

Questions:
1. During a sale, prices were marked down by 20%. The sale price of an item was $84. What was the original price of the item before the discount?


2. A shop increased its workforce by 25%. If 240 workers were working after the increase, how many worked there originally.
