A boutique drinks company, Elixir Co., monitors the market for its signature organic cold-brew coffee (Product $C$). The income elasticity of demand ($YED$) for Product $C$ is +1.2, and the cross-price elasticity of demand ($XED$) between Product $C$ and a competitor's premium iced matcha (Product $M$) is +0.8.

Over the next quarter, average household income in the region rises by 5.0%, while the competitor reduces the price of Product $M$ by 10.0%. Assuming other factors remain constant and the two effects are additive, what is the expected net percentage change in the quantity demanded of Product $C$?
