Candy has a chair rental business. During the weekdays, 60 chairs are rented each day; but during weekends, 100 chairs are rented each day. If this continues, how many chairs in total will Candy be able to rent out in two 4-week months?
During weekdays, a total of 60 x 5 = 
<gadget id="calculator">60*5</gadget>
<output>300</output>
300 chairs are rented.
During the weekends, a total of 100 x 2 = 
<gadget id="calculator">100*2</gadget>
<output>200</output>
200 chairs are rented.
In a week, 300 + 200 = 
<gadget id="calculator">300+200</gadget>
<output>500</output>
500 chairs are rented.
Since there are 4 weeks in a month, 500 x 4 = 
<gadget id="calculator">500*4</gadget>
<output>2_000</output>
2000 chairs are rented in a month.
Thus, a total of 2000 x 2 = 
<gadget id="calculator">2000*2</gadget>
<output>4_000</output>
4000 chairs are rented in two months.
