The school has two options in terms of dealing with the contaminated soil. The first option is to not partake in the soil testing and to simply resurface the play area with a poured-rubber matting that can cover the entire play surface. This will cost, as Sonya indicated in her estimates above, approximately $55,000 – a large chunk of the playground budget. The other option is to perform the soil testing. A municipal worker has estimated that there is a 40% chance that the soil is contaminated.

However, there is a 60% chance that the soil will not be contaminated. Sonya is wondering what they should do and has asked for your help.
REQUIRED
Prepare an analysis of the potential project costs for the following scenarios. Note: There is no need for gravel in the resurfacing scenario.
- Resurface ground without doing soil testing (5 marks).
- Complete the soil testing.In this case there are two outcomes: remove/replace the soil if contaminated & resurface if contaminated.
