Answer:

c. Travis earns a higher rate of return than Alicia.

Explanation:

Both investments are worth $2,400.

Alicia's rate of of return is given by:

[tex]FV=PV(1+r)^n\\2,400=500*(1+r)^{16}\\1+r=\sqrt[16]{4.8}\\r=0.103[/tex]

Travis' rate of return is given by:

[tex]FV=PV(1+r)^n\\2,400=900*(1+r)^{8}\\1+r=\sqrt[8]{2.66667}\\r=0.130[/tex]

Alicia's investment had a rate of return of roughly 10.3% while Travis' investment had a rate of return of about 13.0%.

Therefore, the we can conclude that c. Travis earns a higher rate of return than Alicia.
