Yet another wretched attempt to make a mathematics problem seem relevant to the "real world". In the actual real world, the price a retailer charges for a mixture is NOT determined by the prices charged for the separate ingredients. In the actual real world, the retailer would be more likely to put in about 20% cashews and charge $11.95 per pound for the New CashewEnhanced Trail Mix.
The really sad aspect of this is that with a half a minute of thought the problem writer could have come up with a mixture problem that did make sense in the "real world".
