A farmer is buying feed for his horses. He buys a variety of hay, oats, carrots and sugar cubes. Since sugar cubes are a rare treat, he only buys two 1-pound boxes of them for the whole stable. He only wants enough carrots to feed the horses while the vegetables are fresh, so he buys four 12-pound bags. Hay is the main diet of his horses, so he buys forty-two 75-pound bales. Oats are a staple to supplement the hay, so he buys twenty 65-pound sacks. If his farm truck can carry 2250 pounds at a time, how many trips does the farmer need to transport all the feed?
The farmer is buying 2 * 1 = 
<gadget id="calculator">2*1</gadget>
<output>2</output>
2 pounds of sugar cubes.
He is buying 4 * 12 = 
<gadget id="calculator">4*12</gadget>
<output>48</output>
48 pounds of carrots.
He is buying 42 * 75 = 
<gadget id="calculator">42*75</gadget>
<output>3_150</output>
3150 pounds of hay bales.
He is buying 20 * 65 = 
<gadget id="calculator">20*65</gadget>
<output>1_300</output>
1300 pounds of oat sacks.
The weight of all the feed is 2 + 48 + 3150 + 1300 = 
<gadget id="calculator">2+48+3150+1300</gadget>
<output>4_500</output>
4500 pounds.
Thus, the farmer needs 4500 / 2250 = 
<gadget id="calculator">4500/2250</gadget>
<output>2</output>
2 trips to transport all the feed in his farm truck.
