Cuesta o Cuestan

Question

For a Spanish paper I was asked to fill in the blank using either cuesta or cuestan. "Las frambuesas ____ treinta y cinco" I think cuestan would fill the blank because frambuesas translates to raspberries with is plural.

My next sentence read... "La salchicha ____ veintiuno" I believe cuesta would go here but I am not sure. Thanks.

Answer 1

You are correct on both. Because "las frambuesas" is plural and third person, you should use the ellos/ellas/uds. form: Las frambuesas cuestan treinta y cinco.

"La salchicha" is singular and third person, and therefore you would use the él/ella/ud. form. "La salchicha cuesta veintiuno."
