Answer 1

C=15000

r1=8%

r2=9%

First year

`AC=15000(1+0.08)^1`
`AC=16200`

Then for the second year

C=16200

`AC2=16200(1+0.09)^1`
`AC2=16200*1.09`
`AC2=17658`

then the amount after 2 years is 17658

then the compound interest is given by

`15000*CI=17658`
`CI=(17658)/(15000)=1.1772`

then

the compound interest is 1.18
