Final answer:

The correct amount that each person pays when Sofia, Marcus, and a third person share the bill equally for a $39 lunch is $13. This is found by dividing the total bill by the number of people (39 ÷ 3 = 13), making the answer option a) x=13.

Step-by-step explanation:

The question asks us to work out the amount x each person pays when Sofia, Marcus, and a third person share a lunch bill of $39 equally. The equation b=3r is mentioned, which suggests that the bill b is to be divided by three people to find the amount each person pays r. We are given options for the value of x, and we need to determine which option represents the correct amount each person pays.



To solve this problem, we can divide the total bill by the number of people sharing it. Using this approach:


  • Total bill (b) = $39

  • Number of people (r) = 3

  • Amount each person pays (x) = Total bill ÷ Number of people

Using the formula:

x = $39 ÷ 3

x = $13

Therefore, the correct option for the amount each person pays is a) x=13.
