Answer:
the total bill is $26.50 + $3.75 = $30.25
Explanation:
Keep in mind that the tip is 15% of the cost of the food.
The tax is 6% of the cost of the food.
Thus, the total bill after tax but before tip is (1.06)($25) = $26.50.
The tip amount is (0.15)($25) = $3.75.
Thus, the total bill is $26.50 + $3.75 = $30.25
