Question

$28 for 7 people

Explanation:

Assuming the problem is to find the cost per person (unit rate):

Step 1: Identify total cost and number of people

Total cost = $28, Number of people = 7.

Step 2: Calculate cost per person

To find the cost per person, we divide the total cost by the number of people. So, the formula is $\text{Cost per person} = \frac{\text{Total Cost}}{\text{Number of People}}$. Substituting the values, we get $\frac{28}{7}$.

Step 3: Simplify the division

$\frac{28}{7} = 4$.

Answer:

The cost per person is $4.
