collects 6 more shells in the morning and 3 more shells in the
afternoon.


What is the percent change in Pilar's shell collection
from the beginning of the day to the end? Show your work.

Answer 1

Answer:

The percent change is 9%

Step-by-step explanation:

When you add 40 + 6 you get 46. 46 + 3 you get 49.

49/100 is the usual of a percentage. She already has 40 shells. So there is a 9% different change in her collection. If they ask for a positive or a negative change, it is a positive change since you are adding by 9% to the collection.
