Answer:
the portfolio´s beta is 1.65
Explanation:
when the individual calculation of beta has been given, is possible to aggregate them as a weigthed average, so it is possible to apply te next formula
[tex]Beta Portfolio=w_{1} *\beta _{1}+ w_{2} *\beta _{2} + .... + w_{n} *\beta _{n}[/tex]
where w is the weigthed value for each asset, in this particular case we have:
[tex]Beta Portfolio = \frac{50.000}{100.000}*1.50 +\frac{50.000}{100.000}*1.70[/tex]
so with this result we get 1.65
