The graph shows the hourly revenue (y-axis) with respect to changes (decrease) in price of car wash (x-axis).
We want to know the revenue when there is no price change of a car wash.
When, in the x-axis, there is no price change (decrease)?
The point where x=0 (meaning no price decrease).
Looking at y axis (revenue) when x=0, we see the y-intercept is $200. This is the hourly revenue when there is no decrease in price. Third answer choice is correct.
ANSWER: $200
