Kianna and three friends went out to dinner together. the total bill was $58.49. if they each agreed to pay an equal share of the bill, estimate the amount each person will pay

  $15.00 per person.

Explanation:

 Given that there are "4 people" (that is, "Kianna and three friends");

and a total of "$58.49" ; to be divided equally among 4 (four) people;

 we are asked to estimate the amount that EACH person will pay.

For an ESTIMATE,  $58.49 is ABOUT $60.00; or "60 dollars". ;

and (60 dollars) / 4 = 15 dollars {$15; or $15.00}. 

60/4 = 15;  or 60/4 = (60÷2)/(4÷2) = 30/2 = 15.
