First, we need to calculate the total cost of the food Jayani bought.
Total cost = Pounds of food × Price per pound Total cost = 8.4 pounds × $5.92 per pound = $49.73
Next, since Jayani is splitting the total cost evenly among herself and three friends, there are a total of 4 people.
Amount each person pays = Total cost ÷ Number of people Amount each person pays = $49.73 ÷ 4 = $12.4325
Rounding this to the nearest penny:
Amount each person pays = $12.43
Therefore, the correct answer is $12.43.
