Answer:
$408
Step-by-step explanation:
subtract 30 from 540 to get 510
then divide 510 by 5 or divide 510 by 100 then multiply by 20
----------------------------------------------------------------------------------------------------------------
510 divided by 5 is 102
or
510 divided by 100 is 5.1 which then you multiply by 20 to get 102
----------------------------------------------------------------------------------------------------------------
102 is equal to 20% of 510 so you subtract 510 by 102 to get 408
