A florist harvested $49 \mathrm{~kg}$ of flowers from the field. The kilogram of flowers can be sold immediately for $\mathrm{R} \$ 1.25$ or, later, after the flowers are dehydrated, for $R \$ 3.25$. The dehydration process causes the flowers to 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 a total of $49 \times 1.25 = 61.25$ reais. The weight of the flowers after dehydration is

$$
\left(1-\frac{5}{7}\right) \times 49=\frac{2}{7} \times 49=14 \text{ kg}
$$

Therefore, selling the dehydrated flowers, she earns a total of $14 \times 3.25 = 45.50$ reais. Thus, the florist earns more without the dehydration process.
