While he was surfing the Internet to look for a good deal, Mr Yeo chanced upon the eBrochure of the PC Show 2011 in June.

Next, Mr Yeo went to the Challenger Computer Store, site and found the same product but offering at a lower price!

(a) To answer to the first question, we would find the difference = $129 - $109
ReplyDeletei.e. PC Show Price minus Non-member's price
Difference = $20
In this case, we use the PC Show Price as the original price (that Mr Yeo saved from)
Hence, percentage saved = $20/$129 X 100%
= 15.5% (3SF)
(b) Difference = $129 - $85
= $44
Percentage saved (if Mr Yeo is a member)
= $44/$129 X 100%
= 34.1% (3SF)
