Serhud [2]

Answer:

Number of games = 4

Step-by-step explanation:

Let the number of games = x

Family Bowling Alley charges $1 for shoes and $4 dollars per game

If x games is played

Cost= 1+4(x)

Knight Owl Bowling charges $2 for shoes and $3.75 per game.

If x games is played

Cost = 2 + 3.75(x)

When the both cost are equal

1+4(x)= 2+3.75(x)

4x-3.75x = 2-1

0.25x = 1

X= 1/0.25

X= 4

Number of games = 4

emmainna [20.7K]

Answer:

Part A. Rate of change $ 50

The initial value of Neil's business is $ 1,200

Part B. x = 1200 + 50y

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Year Annual Tutoring Fee

2005 $ 1,200

2008 $ 1,350

2. What is the rate of change and initial value for Neil’s business? How do you know?

Rate of change = (Annual Tutoring Fee in 2008 - Annual Tutoring Fee in 2005)/(2008 - 2005)

Replacing with the values we have:

Rate of change = (1,350 - 1,200)/3

Rate of change = 150/3 = $ 50

The initial value of Neil's business is $ 1,200

3. Write an equation in slope-intercept form to represent the fees that Neil charges each year.

Let x to represent the the fees that Neil charges annually and y to represent the number of years after 2005, we have:

x = 1200 + 50y
