Armando is a barber. He gets 40% of what each of his customers is charged. If the

customer leaves a tip, Armando gets 100% of the tip. How much does Armando earn on an
$8.50 haircut if the customer tips him $1.30?

$6.4

so, if he gets 40% of a thing, that means he gets a reduced price.


to conduct sales tax, we need to move the decimal places 2 places to the left of the percent, so 40% becomes .40



then, multiply it to 8.50


that equals 3.4

3.4 is how much is taken away from him.


so, we subtract 3.4 from 8.50

that is 5.1. thats how much he gets from this haircut, but he gets a 1.30 tip



add 1.30 to 5.1



we get $6.4. thats how much he gets.
