Answer: Her total bill including tip is $51.75
Step-by-step explanation:
Hi, first, we have to multiply the cost of the meal by the tip percentage in decimal form (percentage divided by 100).
Mathematically speaking:
45 x (15/100) = 45 x 0.15 = 6.75 tip amount
Finally, add the amount of the tip to the meal's cost.
45 +6.75 = $51.75
Her total bill including tip is $51.75
