c=$16.45
c=$17.25
c=$28.05
c=$15.65
To find the cost of downloading 36 songs, we only need to substitute 36 for s in the given equation:
c = 2.85 + 0.40s
c = 2.85 + 0.40(36)
c = 2.85 + 14.4
c = 17.25
Therefore, the cost of downloading 36 songs is $17.25.
To find the cost of downloading 36 songs using the given equation, plug in the value of s as 36:
2.85 + 0.40(36) = c
Now, solve the equation:
2.85 + 14.4 = c
= 17.25 = c
Therefore, the cost of downloading 36 songs is c=$17.25.
