Kate is baking cookies using a recipe she found online. Several of the measurements are given in grams, but she needs them in ounces instead. The recipe notes that $$8$$ ounces is $$226.8$$ grams.
Kate uses this information to determine an equation that will convert between the two units of measurement. However, she is unsure what the equation should be. She comes up with two equations: $$z=28.35g$$ or $$g=28.35z$$, where $$z$$ is the number of ounces and $$g$$ is the number of grams.
