You can put this solution on YOUR website! 1. Calculate the simple interest earned if a deposit of $ 14,000 is left for 12 years at an interest rate of 5% .
I = P*r*t
I = 14000*0.05*12 = 140*5*12 = 140*60 = $48400
-------
b. Calculate the number of years for $80,000 when invested at the rate of 5% will give an interest of $28,000.
-----
28000 = 80,000*0.05*t
28000 = 800*5t
280 = 40t
t = 7 years
--------------------
2. solve 1 4/5 x 3/6 ÷ 2 1/4 =
= (9/5)(3/6)/(9/4)
= (3/5)(3/2)/(9/4)
= (9/10)/(9/4) = 4/10 = 2/5
