A family eats at a restaurant. The bill is $42. The family leaves a tip and spends $49.77.
1. How much was the tip in dollars?
2. How much was the tip as a percentage of the bill?
Because the total is 49.77 and the total is the bill + tip, then the tip is 49.77 - 42 or $7.77. To find the percentage, we just calculate 7.77/42 as a percentage to get 1.11/6 = (111/6)% or 37/2 percent or 18.5%
