NMR Spectroscopy Question

Given the compound: C18H24O3

And the information of the Hydrogen and Carbon NMR Spectroscopy

1H: 10.1, doublet, 1; 7.2, singlet, 1; 2.4, quartet, 1; 1.5, quint, 2; 1.2, t, 3

13C: 199, 130, 125, 31, 23, 20

1. Calculate degree on unsaturation

2. Draw 1H and 13C NMRs. Assign a fragment to each peak and justify your choice using tools such as the N+1 rule

3. Draw a structure of your unknown

4. If there is more than one structure possible for your unknown please show both and justify our choice.

This is all the given information.
