2025 CCHY PRELIMS P2 Q9

Irene is looking to buy furniture from EKAYA. She identifies the following items from the catalogue that she needs to purchase, and lists down the approximate amount of time that she will take if she assembles each item.

1. Calculate the total cost of the furniture that Irene intends to buy.[1]
2. Irene has $1000 EKAYA credits from a lucky draw that allows her to make a one-time purchase on the EKAYA online store. Irene lives on the 4th floor of an old estate that does not have lift access. She has back issues and would have difficulties handling weight above 25 kg. She also wants to wall-mount all the folding chairs, but she does not have a drill. She does not want to pay more than $110 out of her pocket. She does not want to spend more than 80 minutes assembling on her own. Suggest how Irene could minimise both the costs spent and the time for assembly for all the furniture purchased. Justify all the decisions you make and show your calculations clearly.[8]

   Delivery

   Assembly

   Home delivery is \(\$35\) for orders above \(15\text{ kg}\). EKAYA will pick and deliver as many products as required. Delivery typically takes place within \(2\text{–}\hspace{0.5em}5\) days from the date of order. For home delivery, an additional flat rate of \(\$20\) applies if there is no lift access, or if items cannot fit in the lift, at an address in a building from the 3rd floor onwards. This service applies up to the 5th floor only.

   All other furniture that requires assembly: \(20\%\) of the original product's retail price. Drilling services are included as part of the assembly services. A \(\$5\) charge per drilled hole applies to products which require wall-mounting and where assembly service has not been booked.

   All costs are subject to 9% GST.
