In all problems involving days, a 360 -day year is assumed. When annual rates are requested as an answer, express, express the rate as a percentage, correct to three decimal places, unless directed otherwise. Round dollar amounts to the nearest cent. If you paid $ 120 to a loan company for the use of $ 2 , 000 for 90 days, what annual rate of interest did they charge?
