Given the statement:
A scanner scanned 72 photos in 8 minutes.
Determine how many photos can it scans in a constant rate after 23 minutes.
Solution:
In order to determine the number of photos scan after 23 minutes, we must first solve the unit rate by dividing 72 with 8.
= 72 photos/8 minutes
= 9 photos per minute
Multiply 23 minutes by 9.
= ( 9 photos per minute)(23 minutes)
= 207 photos
Final answer:
= 207 photos
