Present value = $25,500
N = 3 years
Future value = $32,130
FVF(i%, 3 years) = 32,130/25,500
= 1.26
Hence, I = 8% (using future value table)

Deduce the structure of this ketone by its proton NMR, and
assign the appropriate peaks.
The options for the unknown ketone are: 2-butanone, 4-pentanone,
4-methyl-2-pentanone, cyclopentanone, 2-heptanone, d-l,
3-methylcyclohexanone, 2-octanone, cycloheptanone, acetophenone,
and butyrophenone.
Beside the photo, no additional information was given, including
more specific multiplicity of peaks. However, I am almost certain
that the correct structure is d-l, 3-methylcyclohexanone, I am just
having trouble assigning the peaks.
