Jody and Karen went to lunch. Jody's lunch cost $11.73 witch tax. Karen's lunch cost $13.35 with tax. If they each pay for their own meal and split a 20% tip on the total bill in half, how much did Jody's lunch cost her?

Jody's lunch cost her $14.24 including the tip amount.

Step-by-step explanation:

Jody's lunch cost: $11.73

Karen's lunch cost: $13.35

Total cost = $11.73 + $13.35

= $25.08

Tip amount = 20% of $25.08

= $5.02

Dividing tip into two division: $2.51 per person

Jody's lunch cost including tip = $11.73 + $2.51

=$14.24

Jody has to pay $14.24 for total after splitting the tip amount with Karen.
