Problem 1 :
The total cost y (in dollars) of a gym membership after x months is given by
y = 45x + 75.
What is the total cost of the membership after 9 months?
Problem 2 :
Your annual membership fee to a nature society lets you camp at several campgrounds. Your total annual cost y (in dollars) to use the campgrounds is given by
y = 5x + 35
where x is the number of nights you camp. What do the slope and y-intercept represent?
Problem 3 :
Bowling alleys often charge a fixed fee to rent shoes and then charge for each game you bowl. The function
C(g) = 3g + 1.5
gives the total cost C (in dollars) to bowl g games. What is the cost to rent shoes? What is the cost per game?
Problem 4 :
You purchase a 300 minute phone card. The function
M(w) = -30w + 300
models the number M of minutes that remain on the card after w weeks. Describe how to determine a reasonable domain and range. Graph the function. How many minutes per week do you use the card?
Problem 5 :
An honor society has $150 to buy science museum and art museum tickets for student awards. The numbers of tickets that can be bought are given by 5s + 7a = 150 where s is the number of science museum tickets (at $5 each) and a is the number of art museum tickets (at $7 each). Graph the equation.
1) So, $480 is the amount for membership after 9 months.
2) So, the membership fee is $35 per year.
3) Cost to rent shoes = 1.5, Cost per game = 3
