You can calculate the food cost and then calculate the tax and gratuity and add them to the cost of food to get the final cost to the customer.
The total amount that the customer will pay is given by
Option B: $65.10
How to find the percentage from the total value?
Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
Using the above method to get the total amount paid by the specified customer
Cost for food = $7.39 + twice of $16.99 + $5.29 + twice of $2.30
Cost for food = $51.26
Calculating tax on it (7%)
Tax = [tex]\dfrac{51.26}{100} \times 7 \approx \$3.59[/tex]
Calculating gratuity (20%)
Gratuity = [tex]\dfrac{51.26}{100} \times 20 \approx \$10.25[/tex]
Total final amount = $51.26 + $3.59 + $10.25 = $65.1
Thus,
The total amount that the customer will pay is given by
Option B: $65.10
