Analytic expressions for distance-redshift relations that have been corrected for the effects of some inhomogeneities in the Friedmann-Robertson-Walker (FRW) mass density are used to illustrate the significance of inhomogeneities in a determination of q₀ made by using Type Ia supernovae. The value of q₀ inferred from a given set of observations depends on the fractional amount of matter in inhomogeneities and is up to 50% larger than that obtained by using the standard Mattig m-z result for pure-dust FRW models.
