About 121.25
Step-by-step explanation:
Step 1: Interpret x and y
y is the number of accidents that occur = ?
x is the speed = 60 km/h
Step 2: Substitute value of x in the equation
y=0.0875x² - 10.5x + 436.25
y=0.0875(60)² - `10.5(60) + 436.25
Step 3: Find the value of y
y=0.0875(60)² - `10.5(60) + 436.25
y = 121.25
Therefore, the right answer is the last option which is 'about 121.25.'
