grigory [225]

Answer : 4.8 florins can you exchange for your 4 guilders.

Solution : Given,

The current exchange rate for every 2.4 florins is 2.0 guilders

The exchange rate is 2.0 guilders for every 2.4 florins

The exchange rate is 1 guilders for every \frac{2.4}{2.0} florins

The exchange rate is 4 guilders for every \frac{2.4}{2.0}\times 4=4.8 florins

Therefore, the 4.8 florins can you exchange for your 4 guilders.
