higher fee per game
higher entrance fee
higher total cost for 8 games

​

Answer 1

Answer:

Part a) Higher fee per game Arcade A

Part b) Higher entrance fee Arcade B

Part c) Higher total cost for 8 games Arcade B

Step-by-step explanation:

Let

x------> the number of games

Arcade A

we have that the linear equation is

$y=0.75x+2$

The fee per game is $0.75

The entrance fee is $2

The cost for 8 games is equal to

$y=0.75(8)+2=\ 8$

Arcade B

Find the linear equation

Let

$A(0,8),B(4,10)$

Find the slope of the line (fee per game)

$m=\frac{10-8}{4-0}=0.50$

The point A is the y-intercept

The linear equation is

$y=0.50x+8$

so

The fee per game is $0.50

The entrance fee is $8

The cost for 8 games is equal to

$y=0.50(8)+8=\ 12$

therefore

Part a) Higher fee per game Arcade A

Part b) Higher entrance fee Arcade B

Part c) Higher total cost for 8 games Arcade B
