<span>The line in the chart in slope intercept form has the equation
y = 25x + 50
Since x is the number of days and y is the total cost, it looks like the rental cost is a linear function of the number of days you've rented the game. So the most logical response is that the rate of change represents "daily rate for renting the game"
Since the actual options from the "drop-down menu" weren't provided, you'll have to select the choice that most closely matches the intent of "daily rate for renting the game"</span>
Answer: It's 48%. See below.
Step-by-step explanation:
By definition, percent means out of a hundred. For instance, 10 percent is 10 out of 100.
One way to make 
a percent is by making the denominator 100. In order to do so, multiply the numerator and the denominator by 4, since 25 times 4 is 100.
= 
= 48 %
This is very simple, and mental math is definitely possible. Hope this help.
Answer:
9 games
Step-by-step explanation:
If he purchase 1 game, he spent $12.50. If he purchased 2 games, he spent 2(12.50) = $25.
This means he spent 12.5x for x number of games.
His total spending will be 12.5x + 20. He has $17.50 left on the card from $150.
150 - (12.5x + 20) = 17.5
150 - 12.5x -20 = 17.5
130 - 12.5x = 17.5
-12.5x = 17.5 - 130
-12.5x = -112.5
x = 9
