Final answer:
It will take approximately 14.4 minutes to complete the order for 8 sandwiches. The closest option is A. 14 minutes.
Step-by-step explanation:
To determine how long it will take to complete the order for 8 sandwiches, we can use the given information that it takes 9 minutes to make 5 sandwiches. We can set up a proportion to solve for the unknown time:
9 minutes = 5 sandwiches
x minutes = 8 sandwiches
Cross-multiplying:
9 * 8 = 5 * x
72 = 5x
Dividing both sides by 5:
x = 14.4
So, it will take approximately 14.4 minutes to complete the order. Since time is usually measured in whole numbers, the closest option is A. 14 minutes.
