Question

7. You are planning a camping trip. The campsite you want to rent charges a $15 fee to reserve the site, plus an extra $3 per day.
Part I: Define your variables and write a linear equation in slope-intercept form to represent the cost of the campsite.

Part II: Explain what the point (2, 21) means in the context of this problem.

(Hint: your answer should be a full sentence and include the words "days" and "dollars").

Answer 1

Part I:
Let d = number of days and C = total cost in dollars.
The cost in slope-intercept form is C = 3d + 15.

Part II:
The point (2, 21) means that renting the campsite for 2 days costs 21 dollars.
