Answer:
1) Look at the equation. When looking at the problem equation, identify the base (b), exponent (y), and exponential expression (x).
Example: 5 = log4(1024)
b = 4
y = 5
x = 1024
2) Move the exponential expression to one side of the equation. Set the value of your exponential expression, x, to one side of the equal sign.
Example: 1024 = ?
3) Apply the exponent to the base. The value of your base, b, needs to be multiplied by itself by the amount of times indicated by your exponent, y.
Example: 4 * 4 * 4 * 4 * 4 = ?
This could also be written as: 45
4) Rewrite your final answer. You should be able to rewrite the logarithm as an exponential expression now. Verify that your answer is correct by making sure that both sides of the equation are equal.
Example: 45 = 1024

Answer:
The rate of change is
or 1.75. That shows that the cost per video game is $1.75
Step-by-step explanation:
The change in y over change of x or slope can be calculated using the equation:
so take the last two points: (10, 25) and (15, 33.75).
33.75-25=8.75
15-10=5
8.75/5=<u>1.75</u><u> </u><u>(7/4)</u>
x=video games
y=total cost
Since slope is change in y (cost) per change of x (video games), the answer is:
1.75 cost per video game
