Calculate interest for each bank and identify which bank gives Melvin the better deal? (Use the Table provided.) (Do not round intermediate calculations. Round your answer to the nearest cent.)
Mystic $
Four Rivers $
Better deal (Mystic or Four Rivers)
The interest offered by Mystic is computed as shown below:
Future value is computed as follows:
= Present value (1 + r)n
= $ 11,200 x (1 + 0.14 / 2)9 x 2
= $ 11,200 x (1 + 0.07)18
= $ 37,855.24149
So, the interest amount will be as follows:
= $ 37,855.24149 - $ 11,200
= $ 26,655.24 Approximately
The interest offered by Four Rivers is computed as shown below:
Future value is computed as follows:
= Present value (1 + r)n
= $ 11,200 (1 + 0.12 / 4)9 x 4
= $ 11,200 (1 + 0.03)36
= $ 32,460.71727
So, the interest amount will be as follows:
= $ 32,460.71727 - $ 11,200
= $ 21,260.72 Approximately
So, as can be seen the Mystic Bank gives the better deal
