A florist harvested $49 \mathrm{~kg}$ of flowers from the field that can be sold immediately for $R \$ 1.25$ per kilo. The florist can also sell them dehydrated for 2 reais more per kilo. The dehydration process makes the flowers lose $5 / 7$ of their weight. Which type of sale is more profitable for the florist?
If the florist sells the flowers without dehydrating them, she will earn $49 \times 1.25=61.25$ reais.

The weight of the flowers after dehydration is $\frac{2}{7} \times 49=14 \mathrm{~kg}$. Therefore, selling the dehydrated flowers, she earns $14 \times 3.25=45.50$. Thus, the florist earns more without the dehydration process.
