Answer 1

20% of 85= 17

tip = $17

b). total of dinner bill is $85

Total of dinner bill plus tip is $102 = ($85 + $17 )

Answer 2

a) actual tip amount is $17

b) Total of dinner is $102.

Explanation:

Given:

Dinner bill = $85

Tip for server = 20%

a) We need to find the actual tip given to server as it is in percent form.

To find actual tip we will divide the tip given to server in percent with total dinner bill and then multiply it with hundred.

Actual Tip amount =
`(20)/(100) * 85 = (1700)/(100)\ =\$17`

In Calculator first we will put 20 multiplied 85 we get 1700 and then in Calculator we will put 1700 and then divide by 100 we get $17

Hence the actual tip amount is $17.

b) We need to find the total of the dinner.

To find total of the dinner we will add dinner bill with actual amount paid to server.

Total of dinner = Dinner bill + Actual tip amount = $85 + $17 = $102

In Calculator we will first put the number 85 and then add 17 with it which gives 102

Hence Total of dinner is $102.
