Answer:
Her total bill including tip is $51.75.
Explanation:
Gabriela has dinner at a cafe and the cost of her meal = $45.00
She wants to leave a tip = 15% of the bill
= 0.15 × 45 = $6.75
15% of her bill is $6.75
Now we add the bill amount and her tip
= 45 + 6.75 = $51.75
Her total bill including tip is $51.75
