number of rocks Divya has after she collects rocks on n nature hikes.

What is the answer pls pls pls

35 +

Step-by-step explanation:

Number of rocks present with Divya = 70

Half of the rocks are donated.

i.e. 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 =

For each nature hike, number of rocks collected = 3

Number of rocks collected from nature hikes = Number of nature hikes Number of rocks collected from each nature hike

Number of rocks collected from nature hikes = 3 =

Expression to represent the number of rocks collected after collecting rocks from 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 +
