Learn Spanish (Latin America): ¿Cuánta comida hace la abuela? - How much food does the grandmother make?

The word for "how much" has to match the noun it describes. Because comida (food) is feminine and singular, you must use the feminine singular form, cuánta.

Where is the word for "does" in this sentence?

Spanish doesn't use helper words like "does" or "do" to form questions! The single verb hace covers "makes", "is making", and "does make" all on its own.

Why is the order hace la abuela instead of la abuela hace?

In Spanish questions, it is very common to swap the order and put the verb (hace) before the person doing the action (la abuela). Literally, the sentence is structured as "How much food makes the grandmother?"

I thought the verb hacer meant "to do". Why does it mean "make" here?

The verb hacer is very flexible and translates to both "to do" and "to make" in English. You can easily tell which one it is from the context. Since the grandmother is preparing comida (food), "make" is the right translation.
