Answer:
a. $45.00
b. $53.10
Explanation:
Part A:
Original price of the meal = $60.00
25% discount on $60.00 = 25/100 * $60.00 = $15.00
New price of the meal = Original price - Discount = $60.00 - $15.00 = $45.00
Part B:
New price of the meal after the discount = $45.00
18% tip on $45.00 = 18/100 * $45.00 = $8.10
Final cost of the meal including the tip = New price + Tip = $45.00 + $8.10 = $53.10
So, the final cost of the meal, including an 18% tip, is $53.10.
