Chi -squared Fitting problem

Could anyone here on this newsgroup help solve this disagreement
over what the results of these following calculations will be..

A) Where z=0 and s=1.1 in the formula w=s(1+z), does w = 1.21?

B) Where z=0 and s=1.1 in the formula w=s(1+z), does it follow
that s=1.21?

C) In this chi square fitting formula below ....
I(t) = Imax * ( fR((t-tmax)/s(1+z)) + b )
where z=0 and s is unknown, is it possible to calculate that s=1.21
just by looking at the formula above ? Or to calculate s does one have
to perform the chi squared fitting function?

thanks ahead
