Multi-step problems with percents

Peter took one of his friends out to lunch. The lunches cost $100 and he paid 12% sales tax. If Peter left an 18% tip on the $100, how much in total did he pay?

First find the tax. Write 12% as the decimal 0.12 before using it in the equation.

tax	=	tax percentage × amount

	=	0.12 × 100

	=	12

The tax was $12.

Now find the tip. Write 18% as the decimal 0.18 before using it in the equation.

tip	=	tip percentage × amount

	=	0.18 × 100

	=	18

The tip was $18.

Finally, find the total cost.

total cost	=	cost + tax + tip

	=	100 + 12 + 18

	=	130

The total cost was $130.
