A company has a profit of $6 \%$ on the first $\mathrm{R} \$ 1000.00$ reais of daily sales and $5 \%$ on all sales that exceed $\mathrm{R} \$ 1000.00$ reais, on the same day. What is the company's profit, in reais, on a day when sales reach $\mathrm{R} \$ 6000.00$ reais?
(a) 250
(b) 300
(c) 310
(d) 320
(e) 360
The correct option is (c).

For the first $\mathrm{R} \$ 1000.00$, the company makes a profit of $1000 \times 6\% = 60$ reais, and for the remaining $\mathrm{R} \$ 5000.00$, the profit is $5000 \times 5\% = 250$ reais. Therefore, the company's profit for that day is $\mathrm{R} \$ 310.00$.
