Estimate the total dollar amount of online sales for fruits and vegetables per year in NYC.

To estimate NYC's annual online fruit and vegetable sales, I would break down the problem by first determining the number of households in NYC. Then, I'd estimate the percentage of these households that purchase produce online. Finally, I would estimate the average annual spending per household on online produce purchases. Multiplying these three figures would provide the total annual online sales for fruits and vegetables in NYC. Key considerations would include defining the scope (e.g., fresh vs. frozen, types of online retailers) and clearly stating any assumptions made regarding fees or specific purchasing behaviors.
