Hi Chris, Let me help you. Pagaré la cena. Voy a pagar la cena. Estaré pagando la cena. He pagado la cena. Habría pagado la cena. Debería haber pagado la cena. Let me know if you need more information. Hope it helps

I will pay for the dinner. Pagaré la cena I am going to pay for the dinner. Voy a pagar la cena I will be paying for the dinner Estaré pagando la cena (This is not a natural form in Spanish in order to get the meaning of it as in English, so it should be translated as "tendré que pagar la cena", "yo pagaré la cena" (emphasising the "yo"), or like the one before, "voy a pagar la cena". I have paid for the dinner He pagado la cena I would have paid for dinner. Habría pagado la cena I should have paid for dinner Debería haber pagado la cena

Ricardo many thanks for your exhaustive reply

#1 is correct. the subject is tacit - Yo pagare la cena- is correct. #2 is wrong. Write answer would be "Yo voy a pagar la cena". Your answer, "Va a pagar la cena" implies 3rd person of singular, that in your sentence is also tacit. #3. is wrong. I would translate this also as "Yo pagare a cena". #4. is wrong. You should say: "he pagado la cena" or also "yo he pagado la cena" #5. is wrong. You get the conditional idea here, but wrongly. You should have said:"Yo habria pagado la cena". #6. is wrong. right answer would be: "deberia haber pagado la cena". You are close to the point in some of the sentences, but you need to review some grammar rules and verbs. Keep trying !
