Answer:
$66.78
Explanation:
First, let's find the sales tax 
6% sales tax 
To find the tax amount, multiply the sales tax rate by the price of the meal 
tax rate * meal price 
6%*53
Convert 6% to a decimal by dividing by 100 
6/100=0.06 
0.06*53 
3.18 
Sales tax: $3.18
Next, find the tip amount 
20% tip 
To find the tip amount, multiply the tip rate by the price of the meal 
tip * meal price 
20%*53 
Convert 20% to a decimal by dividing by 100 
20/100=0.20
0.20*53
10.6 
Tip: $10.60 
Lastly, find the total amount. 
Add together the meal price, sales tax and tip. 
meal price + tax + tip 
53+3.18+10.60 
66.78
The total cost of the meal is $66.78
