A model for the mass of residue in a sample uses grams as the value unit
Let t be time in days. Time may vary over non-negative real values, and the multiplier applies every 4 days
\[Q(t)=26+180\,\left(\frac{7}{8}\right)^{\frac{t}{4}}\]
Read the multiplier and the long-run value from the model before calculating
