<human>:  The big bottles of mango juice hold 30 ounces and cost 2700 pesetas each. The small bottles hold 6 ounces and cost 600 pesetas each. How many pesetas would be saved by buying a big bottle instead of smaller bottles for the same volume of juice?
<bot>: How many small bottles are equivalent to one big bottle? ** The equivalent is 30/6=<<30/6=5>>5 small bottles.
How much would 5 small bottles cost? ** Five small bottles at 600 pesetas each is 5*600=<<5*600=3000>>3000 pesetas.
How much would be saved by buying a big bottle? ** The savings is 3000-2700=<<3000-2700=300>>300.
