Use the given equation to find the solution to the following problem.

Question

The equation 2.85 + 0.4s = c gives the cost c in dollars that a website charges for downloading songs. The variable s stands for the number of songs downloaded. Find the cost of downloading 36 songs.

Answer 1

To find the cost of downloading 36 songs, we can substitute the value of s = 36 into the equation 2.85 + 0.4s = c.

Plugging in s = 36 into the equation, we get:

2.85 + 0.4(36) = c
2.85 + 14.4 = c
17.25 = c

Therefore, the cost of downloading 36 songs is $17.25.
