The bill at a restaurant is $30. The customer wants to leave a tip of 18%.

Part A: Find the total of the bill including the tip. Make sure to show your work in an orderly fashion for credit.
Part B: What percent tip would the customer leave if they paid $41.40? Make sure to show all of your work to earn credit

Answer 1

A. 30 * 1.18 = $35.40
B. (41.40 - 30) / 30 = 11.40 / 30 = .38 = 38%

Answer 2

The bill inclusive tip is 35.40 $.
First you calculate how much are 18 % of 30 $.
30 $ : 100% = 0.3 $ ( = 30 cent)
0.3 $ are 1 %
0.3$ x 18 % = 5.40 $
30 $ + 5.40 $= 35.40 $

B:
41.40 $ - 30 $= 11.40 $ ( tip)
30 $ = 100 %
0.3 $ = 1 %
11.40 $ : 0.3 = 38 %
test : 30 $ ( = 100 % ) + 11.40 $ ( = 38 % ) = 41.40 $ ( 138 % )
138 % x .03 $ = 41.40 $
