Answer:
i dont care maybe if you werent a slacker u wouldnt be inn this mess
Explanation:
The first one:
A las tres, Pepe hablo con su novia por teléfono.
The second one doesn’t make much sense, it would be saying: I bought some black pants and my friend Mateo like a lot of money.
I added words in parentheses to make it make more sense:
Yo compré unos pantalones negros y (a) mi amigo mateo le gusta mucho (el) dinero.
The third one:
Después, nosotros comimos cerca de un mercado.
This scentence translates to:
in the store you pay at _________.
the answer is la caja which means the cash register.
Hope this helps :-)
God Bless you!
