X=moira y=mother
x=1/2y-3
x=1/2(76)-3
x=38-3
x=35
Moira is 35 years old.

The number of ways or permutations to select five unordered elements from a set with three elements when repetition is allowed is 243.
According to the given question.
The total number of elements, n = 3
The number of elements to be selected at a time when repetition is allowed, r = 5
Since, we know that " the number of ways or permutations of n things taken r all at a time, when repetition of things are allowed, is
.
Therefore,
The number of ways or permutations to select five unordered elements from a set with three elements when repetition is allowed
= 
= 243
Hence, the number of ways or permutations to select five unordered elements from a set with three elements when repetition is allowed is 243.
