Celine ate brunch at a restaurant. The bill came to $72.80. If she left a 15% tip, what was the total cost of her brunch?

DedPeter [7]

Answer:

$83.69

Step-by-step explanation:

Given the following

Initial Cost of the brunch = $72.80

Percentage tip = 15%

Tip paid = 15% of $72.60

Tip paid = 0.15 * 72.60

Tip paid = $10.89

Total cost of brunch = $72.80 + $10.89

Total cost of brunch = $83.69

Hence the total cost of her brunch is $83.69
