Paige Reeves · Answer 2

i=prt

where i is interest (9000-6000 = $3000 interest)

p is principle ($6000)

r is rate (5.5%) [taking that its 5.5%pa]

t is time

substitute these into the equation

3000 = $6000 x 5.5% x t

t = 3000 divided by (6000x5.5%)

= 3000 divided by 330

t=100/11 years

it would take 100/11 years which is approx 9.1 years
