[HowardvanRooijen]

Can you provide some more details please?

code ：

    using var ctx = new Z3Context();
    var theorem = from t in ctx.NewTheorem<(decimal sz, decimal bz)>()
                  where 0.1752m * t.sz + 0.1252m * t.bz >= 2500 
                  where 0.1221m * t.sz + 0.1084m * t.bz >= 1900 
                  where 0.2008m * t.sz + 0.1718m * t.bz >= 3000 
                  where 0.2209m * t.sz + 0.2428m * t.bz >= 3500 
                  where 0.2811m * t.sz + 0.3519m * t.bz >= 5000  
                  where 0 <= t.sz && t.sz <= 90000            
                  where 0 <= t.bz && t.bz <= 60000               
                  orderby (20.0m * t.sz) + (15.0m * t.bz)
                  select t;
    var (sz, bz) = theorem.Solve();

We believe Z3 suffixes the decimal string with a ? to demonstrate it's been truncated.

https://github.com/Z3Prover/z3/blob/123c44639564455ff09490446b8c0abbca807533/src/util/mpq.cpp#L178-L181

If we trim off the ? then the theorum evaluates to:

sz: 8939.850354678845593236808862, bz: 7457.9729861043630356622291323
