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

As per question,

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.
