Answer:
903

5% of 860 is 43
add that percent to the existing amount
I believe that they typo meant 300 fossils of which 21% are snail shells.

Elmer has 63 fossilized snail shells.
Answer: No
Step-by-step explanation: First, we need to understand that parallel lines are coplanar lines that do not intersect. On the other hand, perpendicular lines are lines that intersect at a right angle.
However, lines can't be both parallel and perpendicular because they either intersect each other at a right angle or never intersect.
So no, two lines can't be both parallel and perpendicular.
