Answer:
35 + [tex]3n[/tex]
Step-by-step explanation:
Number of rocks present with Divya = 70
Half of the rocks are donated.
i.e. [tex]\frac{70}{2} =35[/tex] number of rocks are donated.
Now,
Number of rocks left with Divya = Number of rocks earlier present with Divya - Number of rocks donated
Number of rocks left with Divya = 70 - 35 = 35
Number of nature hikes = [tex]n[/tex]
For each nature hike, number of rocks collected = 3
Number of rocks collected from nature hikes = Number of nature hikes [tex]\times[/tex] Number of rocks collected from each nature hike
Number of rocks collected from nature hikes = [tex]n[/tex] [tex]\times[/tex] 3 = [tex]3n[/tex]
Expression to represent the number of rocks collected after collecting rocks from [tex]n[/tex] nature hikes can be found by adding number of rocks with Divya after donating half the rocks and number of rocks collected from nature hikes.
Therefore, the answer is:
35 + [tex]3n[/tex]
