A bill in the amount of $9.80 between 1 people requires a 15% tip.

How much should each person pay?

Tip Definition:

A tip is a sum of money given by a client or customer
to certain service sector workers for the service they have performed,
in addition to the basic price of the service.

Calculate Total Amount Due with Tip:

Total Amount Due = Bill * (1 + Tip Percent)

Total Amount Due = 9.80 * (1 + 0.15)

Total Amount Due = $9.80 * (1.15)

Total Amount Due = $11.27

Now calculate the total amount due per person:

Total Amount per Person  =  Total Amount Due
  Number of People

Total Amount per Person  =  11.27
  1

Total Amount per Person = $11.27

Calculate Tip Total:

Tip Total = Total Amount Due - Original Bill

Tip Total = 11.27 - 9.80

Tip Total = $1.47

Now calculate the tip amount per person:

Tip Amount per Person  =  Tip Total
  Number of People

Tip Amount per Person  =  1.47
  1

Tip Amount per Person = $1.47

Final Answer:


Total Amount Due = $11.27
Total Amount per Person = $1.47
Tip Total = $1.47
Tip Amount per Person = $1.47
