. Let's say that some consumers' income is m. Let the air
quality that consumers encounter be q1 and the water quality be q2.
The satisfaction obtained by the consumer is u(m, q1, q2) = 2m + q1
+ q1 q2 + 3q2. Let's say income m = 100. The first environmental
quality is (q10, q20) = (1, 1). The environmental quality was
improved by the environmental improvement project and became (q11,
q21) = (2, 5). It is intended to estimate the benefits of
environmental improvement projects.
(1) Calculate the compensation contribution when air quality and
water quality improve simultaneously.

(2) Let's calculate the improvement effect of air quality and water
quality sequentially. Water quality is at its original level and
only air quality has been improved to 2. solve for CS
(3) Air quality is at its original level and water quality is
improved to 5. solve for the CS
