Panel 1:
Melon (cantaloupe) at 12.50 pesos per kilo (something as .70 dollars)

53 pesos (2.79 dollars), marchante (you can roughly transalte "marchante" as dealer, but in Mexico marchante is used for both, the seller and the client)
Panel 3:
53 damn pesos for 3 damn melons? I hope they're worth it
Panel 4:
They were worth every damn penny
