Answer:
Option B is correct.
Step-by-step explanation:
Total bill = $48
Tip = 20%
Amount of tip = 20% of 48
Amount = [tex]\frac{20}{100}*48[/tex]
Amount = 0.2 * 48
Amount = $9.60
Total bill with tip = 48 + 9.60 = $57.60
Dividing by 2 as they are spliting the bill.
Each pays = [tex]\frac{57.60}{2}=28.80[/tex]
Therefore,
Option B is correct.
