Task 1. In the first week, a squirrel collected 84 nuts, in the second week 96 nuts, and in the third week 65 nuts. Another squirrel in the fourth week collected three times more nuts than the first squirrel collected in the second and third weeks combined. How many nuts did the two squirrels collect in total over the four weeks?
Solution. The first squirrel collected $84+96+65=245$ nuts over the three weeks. The second squirrel in the fourth week collected a total of

$$
3 \cdot(96+65)=3 \cdot 161=483
$$

nuts. The two squirrels together collected

$$
245+483=728
$$

nuts.
