ABC Corporation is tying to forecast the effect of an upcoming environmental regulation on the variable costs of one of their key products. The regulation is still being debated in the legislature. There is a chance that the regulation will not be released in time to affect next year's variable costs. ABC management expects the regulation, when it is released, is equally likely to increase variable costs by either 5% or 10%. Currently, the product's variable costs are P140 per unit. Based on these expectations, what is the expected variable cost for ABC's key product next year?
