Dear Math Group:
The first equation below shows a function for u(y) which is
the sum of the products of pi times yi. In the following steps, I
assign values of p and y. How can I get Mathematica to display the
numerical value of u for the given p and y values? When I insert the
u[y] command, I just get a repeat of the equation I have entered.
Thanks for your suggestions. This group is a great help. Darrell
u[y_] := Sum[Subscript[p, i]*Subscript[y, i],
{i, 1, n}]
p = {.3,.4,.3}
y={10000, 20000, 30000}
