Question

The entrance fee to the national park is $15. The campsite fee is $25 per night.

a. Write an equation that represents this situation.
b. Explain what each component of the equation represents.
i. Define the variables. (x = ?, y = ?)
ii. Interpret the slope and y-intercept.
C. Use the equation to find the total cost for 3 nights.

Answer 1

Explanation:

a.) y = 25x + 15

b.) y is the total cost x is the amount of nights stayed 15 is the entrance fee and 25 is the cost per night

i.) x is the amount of nights stayed y is the total cost

ii.) slope (or m) is 25 y-intercept is 15

c.) plug in 3 for x

y = 25(3) + 15

y = 75 + 15

y = 90

its $90 for 3 nights

hope this helps <3
