Restaurant 1

B. 

Restaurant 2

C. 

Restaurant 3

D. 

Restaurant 4

Answer 1

To determine which restaurant charges the least amount of money per fry, we need to calculate the cost per fry for each restaurant. We can do this by dividing the cost of the fries by the number of fries in each order.

1. Restaurant 1:

   • Cost: $1.99
   • Number of Fries: 22
   • Cost per fry: \( \frac{1.99}{22} \approx 0.0904 \)

2. Restaurant 2:

   • Cost: $1.49
   • Number of Fries: 24
   • Cost per fry: \( \frac{1.49}{24} \approx 0.0621 \)

3. Restaurant 3:

   • Cost: $2.49
   • Number of Fries: 43
   • Cost per fry: \( \frac{2.49}{43} \approx 0.0579 \)

4. Restaurant 4:

   • Cost: $2.89
   • Number of Fries: 48
   • Cost per fry: \( \frac{2.89}{48} \approx 0.0602 \)

Now we'll summarize the costs per fry:

• Restaurant 1: $0.0904
• Restaurant 2: $0.0621
• Restaurant 3: $0.0579
• Restaurant 4: $0.0602

The restaurant with the least amount of money per fry is Restaurant 3, charging approximately $0.0579 per fry.

The answer is: C. Restaurant 3
