Question

kathryn and three of her friends went out to eat. they decided to split the bill evenly. if each person paid $13, which equation will tell you the total amount of the bill? a \\(\frac{4}{x}=13\\) b \\(4x = 13\\) c \\(\frac{x}{3}=13\\) d \\(\frac{x}{4}=13\\)

Explanation:

Step1: Count total people

Kathryn + 3 friends = 4 people

Step2: Define total bill as $x$

Total bill split evenly: $\frac{x}{\text{Number of people}} = \text{Amount per person}$

Step3: Substitute known values

Number of people = 4, amount per person = 13. So $\frac{x}{4}=13$

Answer:

D. $\frac{x}{4}=13$
