The table below shows the quantities demanded of milk per month by four families at various prices.
$$\begin{array} { | l | l | l | l | l | } \hline \begin{array} { l } \text { Price of Gallon of } \\\text { Milk }\end{array} & \begin{array} { l } \text { The Berman } \\\text { Family }\end{array} & \begin{array} { l } \text { The Johnson } \\\text { Family }\end{array} & \begin{array} { l } \text { The Harris } \\\text { Family }\end{array} & \text { The Patel Family } \\\hline \$ 3.00 & 9 & 15 & 12 & 14 \\\hline \$ 4.00 & 8 & 12 & 10 & 10 \\\hline \$ 5.00 & 7 & 9 & 8 & 6 \\\hline \$ 6.00 & 6 & 6 & 6 & 2 \\\hline\end{array}$$
-Refer to Table 4-7. If the four families listed are the only demanders in this market and the price of a gallon of milk increases from $4.00 to $5.00, what is the change in the market quantity demanded?
