Find the simple interest kara owes on a 1.5-year loan of $1,500 at an annual interest rate of 7.5%.

Annual interest 7,5%
halfyear interest x%

 x = 0,5 *7,5/1 = 3,75%

7,5% +3,5% = 11%

$1500 100%
  x 11%

 X = 11*1500/100 = 165

so this mean that $165 is the simple interest what Kara owes on in a 1,5 year
