Answer:
It is growth and the percentage rate of increase is 7.5%
Step-by-step explanation:
The exponential equation is as follows;
y = 550(1.075)^x
Now, I can identify that the exponential equation is that of growth.
This is because what is in the bracket i.e can be represented as 1+ 0.075
The 0.075 represents the margin of increase as we move on from one value to another
The percentage rate can be gotten by expressing 0.075 as a percentage
That would be expressing is as a fraction
This is just 7.5/100 which means what we have is 7.5%

Answer:the charge for admission is $6 and the cost of a ride is $2
Step-by-step explanation:
Let x represent the charge for admission.
Let y represent the cost of a ride.
An amusement park charges admission plus a fee for each ride. Admission plus two rides costs $10. This means that
x + 2y = 10 - - - - - - - - - - - - - 1
Admission plus five rides cost $16. This means that
x + 5y = 16 - - - - - - - - - - -- - -2
Subtracting equation 2 from equation 1, it becomes
- 3y = - 6
y = - 6/- 3
y = 2
Substituting y = 2 into equation 1, it becomes
x + 2×2 = 10
x = 10 - 4 = 6
