Yak Travel Agency arranges trips for climbing Mount Everest. For each trip, they charge an initial fee in addition to \( \$ 0.15 \) for each vertical meter climbed. For instance, the price for climbing all the way to the summit, which is 3500 meters above the base of the mountain, is \( \$ 645 \).

Let \( y \) represent the fee (in dollars) of a trip where they climbed \( x \) vertical meters.

Complete the equation for the relationship between the fee and vertical distance.

Answer

3. Write the linear equation: y = 45 + 0.15x

Steps

Step 1 :1. Find initial fee: 645 - (0.15 * 3500) = n

Step 2 :2. Solve for n: n = 45

Step 3 :3. Write the linear equation: y = 45 + 0.15x
