Answer:
6*5 = 30
Step-by-step explanation:
64.80xs.5=$162 $162-20=$142 142x1.09=$154.78 The RacerZ costs $142 and the Swiftee costs $154.78
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
