Shara collects shells. She had 20 shells before she went on vacation. On vacation, she found 5 shells per day for 3 days. Then he found 6 shells on the fourth day. How many shells does she have now?
Shara collected 5 x 3 = <<5*3=15>>15 shells for 3 days.
So she collected 15 + 6 = <<15+6=21>>21 shells rom her vacation.
Thus, she now has a total of 20 + 21 = <<20+21=41>>41 shells.
