Answer:

The tax rate is not needed

Total bill cost = $13

Step-by-step explanatio

Given that :

Tip left = 2.60

Tax = 5%

Tip left = 20% of after tax cost:

To calculate the total bill amount, we do not need information about the tax rate.

Since the total amount paid = after tax amount

Tip left = 2.60 is equal to 20% the after tax cost

Let after tax amount = t

Then,

20% of t = 2.60

(20/100) * t = 2.60

0.2t = 2.60

t = 2.60/0.2

t = 13

Hence, total bill is $13
