<span>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</span>

How much interest will she earn in 3 years?
alekssr [168]
For this, the equation is 
90× 1.13³=y
X was replaced with y. Since she is gaining, you have to remember she is going to have 100 percent of what he had before, she will not lose any.
90× 1.13= 129.86
Now, we need to find the amount of interest she gained, so we have to subtract 90 from the total.
129.86-90=39.86
We can also find the answer by completing a small chart.
The first column will be the year. The second will be the amount. The third will be the interest for the year.
1                                                90                                                11.7
2                                                101.7                                           13.22
3                                                 114.92                                        14.94
The total would round to 39.86, so her interest for the 3 year would be 39.86, with her having 129.86 altogether.
