Each additional hour or rental costs $25.
Step-by-step explanation:
Given equation is;
4h+150=250 Eqn 1
Where 150 is the cost for first 2 hours and 4h is the cost for remaining hours.
Total cost = $250
Solving Eqn 1
Subtracting 150 from both sides
Dividing both sides by 4
Each additional hour or rental costs $25.

An exponential function is a function that has the form y = ab^x, where a represents the initial value, and b represents the rate
<h3>(1) How to fill the table</h3>The exponential function is given as:
When x = 0, we have:
When x = 10, we have:
When x = 20, 30 and 40 we have:
So, the complete table is:
Years after 1950 X : 0 | 10 | 20 | 30 | 40
Ticket Price $ Y : 0.50 | 0.90 | 1.60 | 2.87 | 5.14
<h3>(2) The y-intercept and the rate </h3>The prices look reasonable.
The y-intercept is when x = 0.
So, the value of the y-intercept is 0.50
Also, the rate represents a growth.
This is so, because the rate is greater than 1
<h3>(3) The graph</h3>See attachment for the graph of the exponential function
<h3>(4) The prices in 2000 and 2010</h3>When x = 50 and 60, we have:
Hence, the prices in 2000 and 2010 are $9.21 and $16.49
