I am trying to interpolate the value of an object inside a math equation in Pluto.

A MWE could be:

```
begin
avg = 15
md"""
The average would be given by:
``\overline{X} = \frac{\sum_{i=1}^N X_i}{N} = $(avg)``
"""
end
```

However, I am not successful. It works if I move the interpolation to the outside of the math expression. However, this causes the math to display inline and the value to be formatted as plain text.

Can anyone help me?
