Answer: This shows, 'After 4 days, 88 boats will have passed under the bridge'.
Explanation:
Since, According to the question, Jacksonville allows an average of 22 boats per day to pass.
Thus we can say that number of boats is dependent on days and both are varying.
And, a function is the type of y=f(x), where x is independent variable while y is dependent variable.
So, we can take x for representing number of days and y for representing number of boats.
Thus, according to the question, y= 22x.
if we take 4 days i.e. x=4 then y=22×4=88
⇒It takes 4 days for an average of 88 boats.
Which is showing by (4,88) on the given graph.
