The parents of three children, ages 1, 3, and 6, wish to set up a trust fund that will pay X to each child upon attainment of ag
ehidna [41]

Answer:

The equation of <em>Z</em> is: Z=X(v^{17}+v^{15}+v^{12})+Y(v^{20}+v^{18}+v^{15})

Step-by-step explanation:

  • The first child is of age 1 year.

        Then the amount invested for the 1-year old is: Xv^{17}+Yv^{20}

  • The second child is of age 3 years.

        Then the amount invested for the 3-year old is: Xv^{15}+Yv^{18}

  • The third child is of age 6 years.

        Then the amount invested for the 6-year old is: Xv^{12}+Yv^{15}

The one-time investment will be:

Z=Xv^{17}+Yv^{20}+Xv^{15}+Yv^{18}+Xv^{12}+Yv^{15}\\=X(v^{17}+v^{15}+v^{12})+Y(v^{20}+v^{18}+v^{15})
