Answer 1

Answer:

480 ...12%9 of 8000 ÷2...

Answer 2

• P=8000
• r=12
• n=1/2
• t=1/2

$\\ \sf\longmapsto A=P\left(1+\dfrac{r}{n}\right)^{nt}$

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

$\\ \sf\longmapsto A=8000(1+24)^{0.25}$

$\\ \sf\longmapsto A=8000(25)^{0.25}$

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

$\\ \sf\longmapsto A=17840$
