Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
Amount he make for a purchase = $1987.54
Cash back = 2%
Amount of cash back is given by
[tex]\frac{2}{100}\times 1987.54\\\\=\$39.75[/tex]
Rate of interest = 17.75%
Interest of first month will be
[tex]Interest=\frac{P\times R\times T}{100}\\\\Interest=\frac{1987.54\times 17.75\times 1}{100\times 12}\\\\Interest=\$29.39[/tex]
So, Difference between the first month's interest and the reward is given by
[tex]39.75-29.39\\\\=\$10.35[/tex]
Hence, Option 'D' is correct.
