Answer 1

• P=8000
• r=12
• n=1/2
• t=1/2

`\\ \sf\longmapsto A=P\left(1+(r)/(n)\right)^(nt)`

`\\ \sf\longmapsto A=8000\left(1+(12)/(1/2)\right)^{(1)/(4)}`

`\\ \sf\longmapsto A=8000(1+24)^(0.25)`

`\\ \sf\longmapsto A=8000(25)^(0.25)`

`\\ \sf\longmapsto A=8000(2.23)`

`\\ \sf\longmapsto A=17840`
