Answer 1

To find the total cost when a group of friends goes to see a movie, you can use the formula:

\[ \text{Total Cost} = \text{Number of Friends} \times \text{Cost per Person} \]

Given that the cost per person is $7, we can calculate the total cost for each number of friends:

- For 2 friends:
\[ 2 \times 7 = 14 \]
- For 3 friends:
\[ 3 \times 7 = 21 \]
- For 4 friends:
\[ 4 \times 7 = 28 \]
- For 5 friends:
\[ 5 \times 7 = 35 \]

Now, we can write the ordered pairs (Number of Friends, Total Cost):

- (2, 14)
- (3, 21)
- (4, 28)
- (5, 35)

Therefore, the correct set of ordered pairs from the options provided is:

**(2, 14), (3, 21), (4, 28), (5, 35)**
