54. Adrianna hires a carpenter at a rate of 12 dollars per hours to tie and carpet her apartment => it takes the carpenter 1 hour to finish the 8 square feet => so that’s already 12 dollars then she decided to give 18% tip. => 18% =.18 => 12 dollars * .18 => 2.16 dollars Thus, she give 2.1 as a tip => 12 + 2.16 dollars => 14.16 = the total amount she paid to the carpenter.
