Final answer:
The flower shop will take 16 hours to create 40 floral arrangements.
Step-by-step explanation:
To find the number of hours it will take for the flower shop to create 40 floral arrangements, we need to set up a proportion. We know that the flower shop creates 10 floral arrangements every 4 hours. So, the rate at which the flower shop creates floral arrangements is 10/4 = 2.5 floral arrangements per hour.
To find the number of hours it will take to create 40 floral arrangements, we can set up the proportion: 2.5 floral arrangements per hour = 40 floral arrangements / x hours. Cross multiplying, we get 2.5x = 40. Solving for x, we find x = 40 / 2.5 = 16.
Therefore, it will take the flower shop 16 hours to create 40 floral arrangements.
