Question

The cost of making camping reservations in a campground is represented in the table.

2
5
10
Number of Nights (x)
Cost in Dollars (V)
40.00 77.50 140.00
Based on the information in the table, which equation describes the relationship between the number of nights reserved and the cost?
O A y = 20x
O B. y = 37.5x
O c. y = 7.5x + 35
OD. y = 12.5x + 15
The

Answer 1

D: y=12.5x+15

Using the formula to find the slope given two points:
M= 140-40/10-2= 12.5
we can eliminate the other 3 choices without even finding the Y intercept.
