Question

The graph represents the expected hourly revenue, in dollars, y, earned by a car wash for each decrease of x dollars in the price of a car wash.

A graph shows decrease in price (dollar sign) labeled 2 to 20 on the horizontal axis and hourly revenue (dollar sign) on the vertical axis. A line increases from 0 to 4, is constant from 4 to 6, then decreases from 6 to 16.

What is the hourly revenue if there is no decrease in price?

$100
$150
$200
$225

Answer 1

$200

From the graph the revenue at a decrease of $0 (x = 0) is $200 (the y-value where the line starts).
