4 0

Answer:

462 pictures

Step-by-step explanation:

Average (mean) is calculated by adding up all the values and dividing by how many values there are, therefore to have an average 420 pictures daily, the sum of the 5 days must be: 5x420 = 2100

The current sum is: 320 + 564 + 281 + 473 = 1638

Therefore the number for Friday is 2100 - 1638 = 462 pictures.

Hope this helped!
