For this case, the first thing we must do is define variables.
We have then:
x: number of rides
y: total cost
We now write the equations for each park.
For The Thrill amusement park:
y = 5x + 40
For The Splash water park:
y = 3x + 60
Answer:
A system of equations that could be used to determine the solution where the cost per ride of the two amusement parks, and, is the same is:
y = 5x + 40
y = 3x + 60
Assuming the 10 represents the circumference of the circle (not really clear in the pic) then the area of the circle is found by this equation:
Area=c^2/4pi
(C being circumference, the ^2 meaning squared, and pi of course being the infinite number found by Archimedes, but normally calculated as 3.14 or 3.14)
Using that equation (substitute the C for the 10) you get 7.9577
Round this off to about 7.96, or 8. Your choice.
