You go to a restaurant and your bill is $35.00. Your service was excellent so you leave a 20% tip. What was the total amount paid for the bill including the tip?
10%=$1 for every $10 15%=$1.50 for every $10 20%=2% for every $10
10% of the bill would be $3.50(move the decimal to the tens place) 15% of the bill would be $5.25( halve the 10% and add it to the original 10% tip; $3.50+$1.75) 20% of the bill would be $7.00(double the 10% tip)
