Answer:
A. 10105.86 (compound) or 3510 (simple)
B.11905.86 (compound) or 5310 (simple)
Step-by-step explanation:
If its's compound interest:
[tex]1800(1 + \frac{6.5}{100}) ^{30} = 11905.86 [/tex]
[tex]11905.86 - 1800 = 10105.86[/tex]
If it's simple interest:
[tex]6.5 \times 30 = 195 [/tex]
[tex] \frac{1800 \times 195}{100} = 3510[/tex]
[tex]3510 + 1800 = 5310[/tex]
