Answer:

Jill went for dinner

Let the total cost of the dinner = b

He gave 15% tip, then 15%(b) =0.15b

Total cost of the bill = b+0.15b = 1.15b = b

Percentage increase = [tex]\frac{increased bill-original amount of bill}{original amount of bill}[/tex]

                                  = 15%

The cost of the dinner is increased by 15% as he gave the bill.

Therefore, increase of 15% is the same as the percentage of bill.
