Question

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

Answer 1

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
