Shania runs a store that sells fancy chocolates. Each box ofBlack Hole Dark Truffles takes 3 ounces of cocoa and 18 ounces of sugar. Each box ofRaspberry Fungos requires 5 ounces of cocoa, and 9 ounces of sugar. The store needs to immediately use 105 ounces of cocoa and 252 ounces of sugar. If each box ofBlack Hole Dark Truffles costs $10 in expenses, and each box ofRaspberry Fungos costs $16, we want to know how many of each of the fancy chocolates Shania should have the store make to have the least expenses.
