Building numbers

From 31 to 99: tens + y + units, as three words: treinta y uno (31), cuarenta y cinco (45), noventa y nueve (99).
Cien = exactly 100: cien euros, cien libros. From 101 it becomes ciento: ciento uno (101), ciento veinte (120).
Before a masculine noun, uno shortens to un: treinta y un euros.

Prices

Spain uses the euro: el euro, los euros; 100 céntimos = 1 euro.
¿Cuánto cuesta? = How much does it cost? (one thing)
¿Cuánto cuestan? = How much do they cost? (more than one)
Cuesta tres euros con cincuenta. = It costs €3.50.
Cuestan veinte euros. = They cost €20.
Worked example

Translate: The book costs fifteen euros and the bag costs fifty-five euros.

  1. The book costs: el libro cuesta (one thing, so cuesta).
  2. fifteen euros: quince euros.
  3. the bag costs fifty-five euros: la mochila cuesta cincuenta y cinco euros.

Answer: El libro cuesta quince euros y la mochila cuesta cincuenta y cinco euros.

Key idea

Tens: treinta, cuarenta, cincuenta, sesenta, setenta, ochenta, noventa, cien. 31 to 99: tens + y + units. ¿Cuánto cuesta? (one thing) / ¿Cuánto cuestan? (more than one).
