John and his family went out to eat at their favorite restaurant. the bill for the food was $65.00 and they left 20% tip for the server. what was the total cost of their meal including tip

Method 1

65 +  20%  tip = Total cost

so we need 20% of 65

0.2 times 65 = 13

65 + 13 = $78 total cost  

Method 2

65 is 100%

meal cost 120%  (with 20% tip)

65 Times 1.2 = 78
