Answer:

Mr. Chang will have 15714.90 dollars.

Step-by-step explanation:

p = 650

r = 7.8/4/100=0.0195

Number of periods or n = 5\times4=20

Future value formula is : p[\frac{(1+r)^{n}-1}{r} ]

Putting the values in formula we get;

650[\frac{(1+0.0195)^{20}-1}{0.0195} ]

= $15714.90

Hence, Mr. Chang will have 15714.90 dollars.
