Final answer:
To solve this problem using dimensional analysis, option C is the correct choice. By multiplying the number of friends by the number of slices each will eat and dividing by the number of slices per pizza, you can determine the total number of pizzas needed. Then, multiplying by Link's hourly wage gives the number of hours he will need to work.
Step-by-step explanation:
To solve this problem using dimensional analysis, we can use option C. First, we need to determine the total number of slices of pizza needed to feed Link's friends. We can do this by multiplying the number of friends by the number of slices each friend will eat. Next, we divide the total number of slices by the number of slices per pizza to find the total number of pizzas needed. Finally, we multiply the number of pizzas by Link's hourly wage to find out how many hours he will need to work to feed his friends.
For example, let's say Link has 10 friends, each of whom will eat 3 slices of pizza. If there are 8 slices in each pizza, we would calculate: (10 friends × 3 slices per friend) / 8 slices per pizza = 3.75 pizzas. If Link's hourly wage is $15, he would need to work approximately 3.75 hours to feed his friends.
