Start by proving to them that the number 0.57 can be converted into a fraction . A whole number can't exactly be put in to a fraction. 0.57 can be converted to 14.25/25. This information means that 0.57 IS a rational number. Hope this convinced them!
Compound interest
P(1+rate/100)^years
However, this questions would be easier using simple interest with calculations here.
First year — $35000x102% = $35700
Second year — $35700x102% = $36414
Third year — $36414x102% = $37142.28
Note : don’t include the dollar sign.
Do you still need help?!?!
