Answer:
Nora received <u>35</u> purple pins.
Step-by-step explanation:
If Nora received 50 pins, and 70% of the pins were purple, to calculate the number of purple pins Nora received, we must find 70% of 50.
To find 70% of 50, we can multiply 50 by the decimal form of 70%:
Therefore, we can conclude that since 70% of the 50 pins Nora received were purple, and 70% of 50 is 35, Nora received 35 purple pins.
