The current market price for a ton of rice is $325 per ton. 1) Estimate the benefits for each type of irrigation water allocation 2) Estimate the net benefits per acre for each water allocation Cost to Net grow rice Benefits ($/acre) Water Probability Allocation of (acre-feet) Allocation 0.2 2 0.3 3 0.3 4 0.2 benefits (S/acre) Table 2 Crop Yield (ton/acre) 6.5 10 12 11 (S/acre) $3,160 $3,160 $3,160 $3,160 Market Price of Rice (S/ton) $325 $325 $325 $325 3) Estimate the expected net benefits using the probability of allocation and the Net Benefits
